INTRODUCTION TO CHI131
INTRODUCTION TO CHI131
A WORD ABOUT CHI131: CHI131 is CHI101 taught in English. It is part of the larger European strategy of
CLIL (Content and Language Integrated Learning)
in which students are given additional opportunity to practice their English by taking some of their other courses in English besides the usual English language instruction. In French, this stategy is known as
EMILE (Enseignement d'une Matière par Intégration d'une Langue Étrangère).
An English language document on this strategy may be found here. Videos of a French workshop on the same subject may be found here.

A WORD ABOUT THE IMPORTANCE OF BEING SELF-MOTIVATED:
Probably the biggest difference between High School and the University is that the teachers are not constantly giving you homework and collecting it at the University the way they do in High School. That may give you a great feeling of freedom, but that freedom is (in part) illusory. In reality you are being given "enough rope to hang yourself!" The solution is that you have to be self-motivated. Indeed this is something that is on the lips of nearly every University professor when asks what he or she expects of his or her students. And more and more self-motivation is expected as you progress from semester to semester of your undergraduate years! In the case of CHI 131, I would say that you definitely want to come to the lectures and try to understand them (copying them over to reorganize them in a way that it more understandable to you is a good idea), that you want to try Discussion Section exercises as soon as the appropriate material has been presented in lecture if not before (it is OK to read ahead!) It is also a good idea to keep a little notebook with questions that come to your head about the course material and to make sure that each and every one of your questions gets answered. Good luck in this first year at the University!
CHANGES IN RESPONSE TO THE COVID-19 PANDEMIC
CHANGES IN RESPONSE TO THE COVID-19 PANDEMIC
Tuesday 29 August 2023
We are very glad that the COVID pandemic of 2020 seems to be under control. Like just about everyone else we will continue to maintain some innovations from that time. For example, there will be a Discord site for the class. It is a good place for asking questions and getting answers. It has also proven useful for socializing (especially during lock-down but not just!) I am hoping that we will not have to use it for on-line classes (but it might be necessary if I am too sick to come in and lecture.) It was useful during the disturbances of 2022-2023 due to changes in the retirement law.
We may also try to continue a paperless class. That means that class notes and other documents will only be distributed in electronic form (you can print them if you must), homework should be photographed, scanned, or typed, and turned in electronically. Corrections will be done electronically and be returned to you. However midterm and final exams and labs will be in-person.
Besides the other advantages already mentioned, this will allow us to switch rapidly to on-line distance learning should that become necessary for any unforeseeable reason (e.g., if I catch COVID). Certainly I hope that this will not be needed.

CHI131 GRADING, ACADEMIC YEAR 2020-2021
CHI131 GRADING, ACADEMIC YEAR 2020-2021
The course is divided into the main part and the crystal part. Unlike in previous years, there will be no common exams for these two parts.
The main part counts for 70% of your final grade, with 20% of the grade coming from the midterm exam and 50% of the grade coming from the final exam.
The crystal part counts for 30% of your final grade, with 10% of the grade coming from lab write-up and/or homework grades and the other 20% coming from a special crystal midterm.

CM Time Tables
CM Time Tables
I like to leave the previous year's time table so that we can all see how fast we are advancing and approximately where we should be for each lecture. Note however that we are going to have to go faster this year than we did last year (sorry).
2023-2024 CM BIO-INT + CHB-INT + PCMM-INT
2023-2024 CM BIO-INT + CHB-INT + PCMM-INT
This course is divided into two more or less independent parts --- namely crystal structure (xtal) and atomic structure and chemical bonding (atom).
The plan is to devote 2 lectures to the xtal part of the course and 10 lectures to the atom part of the course. (The actual division between xtal and atom lectures may vary.) That makes only 12 lectures total, each lasting 1 1/2 hours.

LECTURE: xtal 1
DAY, DATE, TIME, ROOM: Thu. 2022.09.08 9h45-11h15 DLST-TD E207+E208
COVERED:
We are supposed to only have 2 lectures on Xtals, but somehow I still need to give 3 lectures. The first lecture is the hardest as I need to present the somewhat difficult basic notions of what a crystal is and how we describe it. This time, I tried to prepare some slides before hand, in the hope of going a little faster. These slides were placed on Discord. They may have helped to improve the clarity of my presentation, but (alas) they did not help me go any faster. So here is what I did. (Note that the numbering does not correspond to the slides.
I. Basic Notions
Why crystal is often abbreviated Xtal in English. Macroscopically crystals have beautiful symmetries and well-defined angles. This motivated the idea (e.g., Kepler's snowflake model) that Xtals must be made up of smaller symmetrical units with well-defined angles. Ultimately this would become the notion of the unit cell.
II. 7 Crystal Systems/6 Crystal Families
The primitive unit cell is a parallelpiped whose lengths and angles are the lattice parameters. The associated symmetry may be analyzed in terms of rotational axes (Cn and Dn symmetries). This leads to 5 Xtal familes in 2D and 7 Xtal systems (6 Xtal families) in 2D.
III. Lattice Centering & Bravais Lattices
Bravais considered adding points to the center of faces and inside the unit cell. This is closely related to mirror plane symmetries and inversion symmetries. I therefore took the time to discuss these important symmetry operations. We discussed this in detail in 2D and then just gave the answer in 3D. In addition to the P (for primitive) unit cell, Bravais introduced complex unit cells (C, F, I) which constitute more intuitive representations which help to bring out the crystal symmetry more clearly. There are 14 Bravais lattices in 3D.
Rock candy video. Everyone should know how to make sugar crystals at home!
IV. Mathematics of Periodicity
Definition of an ideal Xtal as an infinitely repeating arrangement of atoms. (Of course, real Xtals are not infinite.) The concept of basis atoms and generating vectors in 2D. Only integer steps are allowed! Now remove the atoms to just see the lattice, which is a sort of template used to generate the Xtal from a set of basis atoms. Illustration in 2D for graphene. This requires 2 basis atoms.

LECTURE: atom 2
DAY, DATE, TIME, ROOM: Thu. 2022.09.08 13h30-15h00 DLST-TD E207+E208
COVERED:
This is the second lecture on Xtal structures. It is easier and more down to earth. However I am not sure that I was as organized as I would have like to be in my presentation of the material. On the other hand, there was a lot of interaction with the students, which I think is a good thing. This was also a time to emphasize how to do calculations with units at every step (i.e., dimensional analysis).
I. The 4 Important Metallic Lattices for Us
simple cubic (SC), body-centered cubic (BCC), face-centered cubic (FCC), and hexagonal closest packed (HCP).
II. Case Study: BCC
I did talk about the difference between ordinary language for describing a box (e.g., faces, edges, and corners) and scientific language (e.g., faces, edges, and vertices).
Coordination number (CN) was defined and it was determined that each atom has a CN of 8 in the BCC Xtal.
We saw how to calculate the # atoms in the unit cell (keeping in the units). It is 2 for BCC.
The concepts of density (FR: masse volumique) and specific gravity (FR: densité) were introduced and we calculated the density of tungsten (W).
We then calculated the atomic packing factor (APF) for the BCC lattice.
Students need to be able to do this type of calculation for the SC and BCC lattices as well.
I emphasized that the students are expected to rederive formula every time they need them. The object is to understand and memorize the least possible.

Anticipated:
O. How much math do we need?
addition, subtraction, multiplcation, division (simplifying fractions) --- everyone needs this
solving 2 equations in 2 unknowns, pythagorean theorem --- also pretty basic
statistics and basic integral differential calculus --- definitely needed by biologists
more advanced calculus, differential equations --- chemists, physicists
We need algebra and just a little bit of calculus but we will also see imaginary numbers and differential equations because this is the mathematics of quantum mechanics. But you will only really be using algebra and a bit of calculus.
Secondary objective: learning to associate equations with graphs.

Textbook
There really is not a good textbook for this course (though my course notes resemble a little a textbook.) The problem is actually very simple: We only cover a small part of what is usually treated in a typical American or Canadian (and I suppose also British) chemistry course. That means that we only cover the first few chapters of a typical General Chemistry textbook.
Nevertheless a textbook has been chosen for this course and may be found at the University Science Library:
[AJ99] Peter Atkins and Loretta Jones, Chemical Principles: The Quest for Insight (W.H. Freeman and Company: New York, 1999) ISBN 0-7167-3596-2
Another excellent textbook in the Science Library is

COVERED:
We had a good look at the pictures of atomic orbitals and their nodal surfaces on Mark Winter's Orbitron.
We then went through
4.2.3. Atomic Orbitals
4.2.3.2. s-, p-, and d-Atomic Orbitals
4.2.3.3. Quantum numbers
4.2.3.2. was done in detail and I think really helped the students to understand the concept of nodal surfaces and how to go from the labels of the d-functions to their drawings. This is a skill which is not difficult but that they need to be taught and need to practice. We only did bits and pieces of 4.2.3.3, because we have not yet treated spin in lecture. But the students did quite well with the quantum numbers. Once spin is introduced in Monday's lecture, we can do a few more of these before moving on to Electron Configurations of many-electron atoms.

4.3.1.5. Resonance Structures
I did this by sending groups of students to the board to work on sets of problems. This turned out to be remarkably interactive and gave me a chance to talk more about formal charges and even a bit about VSEPR.
I assigned all of the VSEPR problems (4.3.2), not to be turned in (I will send them the corrections). That way I am clear to focus on MO theory next week.

TD: 16
DAY, DATE, TIME, ROOM: Wed. 2022.11.30 8h00-9h30 DLST-TD B005
COVERED:
We spent about one hour talking about how the MO and VB orbitals are fundamentally different but also essentially equivalent ways of describing molecules. MO theory is better for physical properties (e.g., ionization and other types of spectroscopy) and VB is better for describing chemical properties (e.g., bonding and chemical reactions). I constructed and discussed MO and VB orbital correlation diagrams for O2 but emphasized that the students are in no way responsible for the VB orbital correlation diagram. I only did it because there was too much confusion between MO and VB orbitals and this seemed to me to be the only way to sort things out for this section. Unfortunately I felt like I was having a dialogue that only included the first row of the class. For the last half hour of class, I asked the front row to just be passive and I only worked with students from other rows. We only did
4.3. Molecules
4.3.5. Valence Bond Theory
4.3.5.2. Valence-Bond Theory (AO Hybridization)
4.3.5.2.a. specify the hybridization of H2C=CH-CCH (only did this part)
So we did not get very far with the actual exercises and this last part was like pulling teeth.

COVERED:
First of all, I was shocked by the very low attendence (60%?) this morning. Normally the International groups never have less than 90% attendence! There is something wrong with this group this year which I hope will change in CHI 231. Also, those students who did come seemed very dispersed and hard to motivate. I cannot help but wonder if this is not some sort of cry for help? If so, I am having difficulty knowing what to do. What we did work on was
4.3. Molecules
4.3.3. Intermolecular Forces
4.3.3.1. Phase change temperatures (exercises worked on board in the reverse order)
4.3.3.2. Solubility and Intermolecular Forces
Exercises 4.3.3.3 and 4.3.3.4 are homework, not to be turned in. I will send the answers.

TD: 16
DAY, DATE, TIME, ROOM: Thu. 2022.12.01 8h00-9h30 DLST-TD E206
COVERED:
First I emphasized that molecular orbitals (MOs) and valence-bond (VB) orbitals are different: MOs are delocalized and used to describe spectroscopy, such as ionization phenomena; VB orbitals are localized on atoms and are used to describe molecular structure and chemical reactivity. Depending upon which use you feel is the most important, either MOs or VB orbitals may feel more real to you.
Next we went over a series of little rules:
(1) Each set of sp^n orbitals consists of n+1 hybrid orbitals.
(a) The sp^3 hybrid orbitals are arranged in a tetrahedron (bond angle 109.5 deg.)
(b) The sp^2 hybrid orbitals are arranged in an equilateral triangle (bond angle 120 deg.)
(c) The sp hybrid orbitals are arranged in a linear arrangement (bond angle 180 deg.)
(2) They are used to describe the n+1 sigma orbitals + lone pair "balloons."
(3) Single bonds are always sigma bonds, double bonds are composed of one sigma and one pi bond, and triple bonds are composed of one sigma bond and two perpendicular pi bonds (e.g., pi_x and pi_y).
(4) The left-over p orbitals are used to form pi bonds:
(a) There are no left-over p orbitals for sp^3 hybridization.
(b) There is one left-over p orbital for sp^2 hybridization, so we expect one pi orbital.
(c) There are two left-over p orbitals for sp hybridization, so we expect two perpendicular pi orbitals (either a triple bond or two double bonds).
I then did several examples H3C-CH3 , H3C-NH2 , H2C=CH2, H2C=O, HCCH, CN(-) etc. emphasizing which type of hybrid orbitals are used, sigma bonds, pi bonds, lone pairs (lps), and the final geometry. Pi bonds were also drawn.
Finally I had the students do
4.3. Molecules
4.3.5. Valence-Bond Theory (AO Hybridization)
4.3.5.a. H2C=CH-CCH , H2C=CH-CH3 , H2C=C=CH2
The emphasis was on specifying how each heavy atom (i.e., not H) is hybridized, which bonds are sigma and which are pi, where the lone pairs are, and how this determines the final 3D geometry.

TD: 1
DAY, DATE, TIME, ROOM: Fri. 2022.09.23 13h30-15h00 DLST-TD D004
COVERED:
Today, with PCM students, we worked on the exercise of section 4.1 : 4.1.1 to 4.1.4 about units.
I have been very active and students were not that much... It's the beginning of the year, they still have to be comfortable with their new environment.
I asked them to start the review exercises about particles, isotopes and quantity of matter for next Thursday.
3 students were missing, all because of COVID. Many students were wearing masks.
Otherwise, I'm pretty certain that they are rather good students and it will be a nice semester teaching to them.

COVERED:
We started with 4.2.2.1 : Electromagnetic radiations
I spent some time to talk about the photoelectric effect and we could
do 4.2.2.2 : Photoelectric effect I and 4.2.2.3 : Photoelectric effect II

TD: 4
DAY, DATE, TIME, ROOM: Thu. 2022.09.29 11h30-13h00 DLST-TD B212
COVERED:
I corrected the exercise about the Compton effect and we started discussing the line spectra: for that, I started to ask them what experimental set up could give a line spectrum and why there are line spectra... It seemed useful as many seemed to be a bit lost. That makes me realize the amount of methodological work they have to do... understanding the system, getting and sorting the useful information... Anyway, I had the feeling that they generally managed to understand the principles of absorption and emission.
We did exercise 4.2.5 Hydrogen Atom and Line Spectra. Some work at a faster pace and are already working on ex. 4.2.7.
Others just skip exercises if they don't manage to do it...I told them that such "avoidance strategy" is not a good one in TD...

COVERED:
We did exercise 4.2.9 about the emission spectra of H and Li2+.
Some have started 4.2.10: absorption spectra
I asked students to look at 4.2.10 and most importantly to carfully read about the lecture you did on Monday and will do on next Monday (next TD is on Thursday), so that se can start the next part about atomic orbitals more easily.
Anyway, I plan to start next TD by discussing with them about what they understood on the topic.

COVERED:
For the two past sessions, We have slowed down with students and are maybe a bit behind you.
Yesterday, 20th/10, we took time to discuss about the concepts of quantum mechanics... wave function, probability density, Schrodinger equation, etc.
Then we started exercices 4.2.3.1.
Today 21st/10, we continued exercise 4.2.3.1 and finished questions a-e. I told them to work on part f and g that I'll correct next time.
Some students are ahead, some are behind... and many seem happy to be told things more than once.

COVERED:
we had to speed up a bit, therefore,
I started to finish exercise 4.2.3.1 (e,f) students had to finish.
We did together 4.2.3.2 about s, p and d orbitals.
We also covered 4.2.3.3 about quantum numbers together: students seemd to be quite comfortable with the quantum numbers.
We then switched to 4.2.4 : Periodic table.
I made a quick introduction on how one can use the solutions for the 1electron atom for a many electron problem (I quickly talked about screening effect) but also introduced the Madelung rule, Hund rule, Aufbau principle and Pauli exclusion principle. We just initiated the first exercise.

COVERED:
We did (in this order):
4.2.4 1 Atomic Electronic Configurations7 and the Periodic Table :
I was nicely surprised to see that they seemed familiar with the electron structure of atoms!
We then switched to 4.2.4.4 about the electron configuration of ions as it was naturally following question (c) of the previous exercise.
We then cam back on 4.2.4.2 Ground, Excited, and Ionized States of an Atom
Some started 4.2.4.3 about the specific stability of 1/2 filled and filled subshells, which gave me the opportunity to explain the phenomenon but not to give a proper correction of the exercise.

COVERED:
After a long break, I started by giving a quick correction to exercise 4.2.4.3 that was left unfinished. We then started with the Lewis dot structure exercises. Students were quite efficient and very comfortable with that part : more than students of previous years, it seemed to me. Some were working way ahead.
We therefore could do :
4.3.1.1 First-Row Lewis Dot Structures.
4.3.1.2 : Arrow Pushing in Organic Chemistry Resonance Structures
4.3.1.3 : Lewis Dot Structures Beyond the First Row
4.3.1.4 : Arrow Pushing in Inorganic Chemistry Resonance Structure

DAY, DATE, TIME, ROOM: Fri. 2022.11.18 8h00-9h30 DLST-TD D004
COVERED:
We finished the Lewis dot structure and started VSEPR, we did :
4.3.1.5 : Resonance Structures
4.3.1.6 : As I wanted to start VSEPR, I explained the Br* + C2H4 reaction (I wanted to show the 1/2 arrows) and asked them to finish it at home
We then switched to VSPER and did 4.3.2.1 (a), (b) and started (c).
I took 5 minutes to return the midterm exams. With an average grade of almost 14.8, that's was a good surprise.

We quickly finished exercises 4.2.3.4 and 4.2.3.5 in order to switch to MO diagrams. I think they are OK with dipoles now.
I took time to re-explain few points and we did 4.3.4.1 Atomic Orbital (AO) Overlaps
and 4.3.4.2 : Hydrogen Compounds.
I insisted that they had to prepare (at least) the next exercise, about F2...

COVERED:
On Thursday 1st/12, as being infected by COVID, we did the TD via discord.I *really* prefer presential teaching.
However, we did 4.3.4.3: diatomic fluorine, 4.3.4.4: First-Row Homonuclear Diatomics.
I skipped 4.3.4.5 and, because we were running out of time, and had to provide the answers (diagram) for 4.3.4.6: MO Diagram for a Heteronuclear Diatomic.
Students were working together in the TD room and communicating with them through Discrd was quite difficult. I don't even know if all of them were present.

COVERED:
This morning, on Friday 2nd/12, we worked on VB theory, via discord again (I'm still at home).
We did 4.3.5.1 Electronic Structure of Butadiene, and 4.3.5.2 : Valence-Bond Theory (OA Hybridization).
I had not time to treat 4.3.5.3: Color and Electronic Structure. I think I'll skip it to focus on intermolecular forces during the last TD.
Again, it's been hard to get some feedback through Discord.

The students do not yet seem to have the idea that they need to look ahead and try the problems before coming to TD. This is slowing us down significantly and I think making it harder for the students to profit correctly from the TD. I asked the students to prepare exercises 4.2.2.7 - 4.2.2.10 for next time.

COVERED:
We discussed the difference between the ''huge'' number of equations in the lectures and the actual number of equations used in the TD exercises. In the process, we returned to Ex. 4.2.2.6 and went over some key concepts.
4.2.2. Light and Spectroscopy
4.2.2.7. Hydrogn atom and Line Spectra --- all except part (f)
I do believe that the students have caught on to the idea that there are only a few equations and that these problems are asking them to use them in increasingly complex ways.
Homework (not to be turned in, I will e-mail the students the answers): Exercises 4.2.2.7 (f), 4.2.2.8, 4.2.2.9, and 4.2.2.10.

Today's TD is a little weird because we jumped around to do parts of exercises that were skipped last week since we had not yet had the relevant part of the lecture. Here is what we did:
4.2.3. Periodic Table
4.2.3.1.c. Ordering of ionization potentials
4.2.3.2.c. Formula for nitrogen atom combined with an element less electronegative than itself.
4.2.3.3.b. Essay question on trends in ionization potentials.
I emphasized once again that the midterm exam would contain questions whose answers would require short essays. I explained that this is really a two step process: (i) identifying patterns or trends and (ii) explaining the trends in terms of electron configurations, shell filling, screening effects, etc.

DAY, DATE, TIME, ROOM: Thu. 2021.11.18 9h45-11h15 DLST-TD B005
COVERED:
I began by answering a question about the formal charges in carbon monoxide and this led into an explanation of dipole moments. These students have also been studying dipole moments in their physics class.
I then went on to lecture, somewhat informally, about VSEPR theory, giving several examples. I explained that they needed to be able to (i) draw the geometries, (ii) put in the angles, and (iii) name the geometry. I also emphasized that the hardest part of the exercise is probably learning all the geometry names.
I then returned to dipole moments with SF4 as an example and finished with the two cases (center of inversion and mutually perpendicular rotational axes) when the dipole moment is necessarily zero.
Homework (not to be turned in): 4.3.2 VSEPR Theory and Dipole Moments (all)

4.3.4.1. Atomic Orbital (AO) Overlaps
4.3.4.2. Hydrogen Compounds
4.3.4.3. Diatomic Fluorine (mostly done but we still need to fill the MOs and calculate the BOIs for the different species)
I finished by explaining the sigma_p/pi switch between N2 and O2 that was not mentioned in lecture but that they students still need to memorize.

DAY, DATE, TIME, ROOM: Wed. 2021.12.01 8h00-9h30 DLST-TD B007
COVERED:
Based upon my experience in previous years, I decided that we should take lots of time to go through valence-bond (VB) theory nice and slowly so that the students can become properly comfortable with the subject. Today we went through:
o Proper hash-wedge drawing of CH4
o Acetone: identifying the hybridization of the carbons and the oxygen, drawing the 3D structure with a maximum of atoms in the plane of the paper, and making sure to represent the angles as accurately as possible in the drawing.
o Butadiene: This was done in lecture and is one of the TD exercises. We went through it very slowly. What geometrical information comes from VSEPR? Draw the sigma-skeleton. Draw the pi-system. What geometrical information comes from VB theory for the pi-system? The pi-system is delocalized over the entire molecule, like a particle in a box. Resonance structures.

COVERED:
First atom TD.
We did all of
4.1. Units
4.1.1. Dimensional Analysis
4.1.1.a. Calculation of volume occupied by an atom of a gas
4.1.1.b. Calculation of the concentration of vinegar
4.1.2. Expressing Composed Units in Terms of Fundamental Units
4.1.2.a. Decomposition of the SI energy unit (1 J) into fundamental units
4.1.3. Fermi Estimations
4.1.3.a. Density of water from a typical atomic radius and the molar mass of water
No homework was assigned.
There was time to talk more with the students before I let them out a little early. (I will not always do this.) They seem to be impressed with the concept of dimensional analysis but they are also unsure of whether they will succeed in doing it themselves. Well, practice makes perfect! We also discussed the change in the lycée program and how that affects them. In the latest form of the system, students are requested to drop one of the key subjects (math, chemistry, ... ) during their last one or two years. One result is that the last chemistry class that some students had was two years ago.

TD: 3
DAY, DATE, TIME, ROOM: Fri. 2021.10.01 13h30-15h00 DLST-TD E205
COVERED:
I began by discussing the photoelectric effect in more detail than usual. I discussed how the level diagram changes when we go from 1-electron atoms to many-electron atoms (more electrons!) to molecules (different distributions of levels, with HOMO and LUMO) to solids (bands!) How the binding energy (BE) of an electron is not the same as the work function (W), but that BE > or = W and some other things. Then we did:
4.2.2. Light and Spectroscopy
4.2.2.2. Photoelectric Effect (I)
So, in a sense, we really slowed down in order to make sure that everyone was understanding!
Homework (not to be turned in, I will e-mail answers):
4.2.2.3. Photoelectric Effect (II)

COVERED:
4.2.2. Light and Spectroscopy

DAY, DATE, TIME, ROOM: Fri. 2021.10.01 13h30-15h00 DLST-TD E205
COVERED:
4.2.2. Light and Spectroscopy
4.2.2.6. Energy Levels and Spectroscopy
This took a remarkably long time for many students to understand. I am worried about this group's progress. We discussed the problem and I asked what we could do? I think I am going to have to accept that this group is slower than my other group and that we may not have time to cover all the material on the midterm in TD before the midterm.
Homework (not to turn in, but I will send answers): 4.2.2.7. Hydrogen Atom and Line Spectra and 4.2.2.8. Hydrogenic Ions and Emission Spectra.
I also asked the students to try Exercises 4.2.2.9 and 4.2.2.10 before next TD.

4.2.3.3. Quantum Numbers, part (d) only
Exercise 4.2.3.2 may be improved by explaining that dz2 really stands for d[z2-(1/2)(x2-y2)]. Only then do you get the nodal surface correctly as well as the signs of the different parts of the orbital.

COVERED:
We jumped around to do parts of exercises that were skipped last week since we had not yet had the relevant part of the lecture. Here is what we did:
4.2.3. Periodic Table
4.2.3.1.c. Ordering of ionization potentials
4.2.3.3.b. Essay question on trends in ionization potentials.
I emphasized once again that the midterm exam would contain questions whose answers would require short essays. I explained that this is really a two step process: (i) identifying patterns or trends and (ii) explaining the trends in terms of electron configurations, shell filling, screening effects, etc.
-----------------------------------------
CHI131dB02 2020-2021 BIO-INT
TD: 11
DAY, DATE, TIME, ROOM: Fri. 2021.10.29 13h30-15h00 DLST-TD E205
COVERED:
I began by talking about the three prototypical bonding types --- namely covalent, ionic, and metallic --- and said that we were mainly thinking in terms of ionic bonding up until this point. Then we did:
4.2.3. Periodic Table
4.2.3.2.c. Formula for nitrogen atom combined with an element less electronegative than itself.
4.2.3.3. The Stability of Filled and Half-Filled Subshells
4.2.3.4. Electronic Configuration of Ions
I then lectured a little bit on Lewis dot structures: I begain with the octet (and double) rule(s) and first applied it to ionic bonding in NaCl. I then explained how it could be extended to include H2 through the idea of the electron pair bond. I emphasized the use of atomic orbital configurations as a way of seeing the pairing of electrons. I did this also for NH3 and showed them how the lone pair arises. Finally we did N2 the way Lewis might have done it with 5 valence electrons coming from each N to give a total of 10 electrons that we need to use to make 5 electron pair bonds. I showed them the process of moving electron pairs into the space between the atoms allows each atom to have an octet. The final result is :N:::N: (a triple bond!) I did not introduce formal charges in this group.

TD: 13
DAY, DATE, TIME, ROOM: Fri. 2021.11.19 13h30-15h00 DLST-TD E205
COVERED:
I began by answering questions about hypervalence and resonance structures. This took a fair amount of time.
I then went on to lecture, somewhat informally, about VSEPR theory, giving several examples. I explained that they needed to be able to (i) draw the geometries, (ii) put in the angles, and (iii) name the geometry. I also emphasized that the hardest part of the exercise is probably learning all the geometry names.
We did not have time to do dipole moments, so that will have to wait until next week.

DAY, DATE, TIME, ROOM: Thu. 2021.12.02 8h00-9h30 DLST-TD E206
COVERED:
Based upon my experience in previous years, I decided that we should take lots of time to go through valence-bond (VB) theory nice and slowly so that the students can become properly comfortable with the subject. Today we went through:
o Proper hash-wedge drawing of CH4
o Acetone: identifying the hybridization of the carbons and the oxygen, drawing the 3D structure with a maximum of atoms in the plane of the paper, and making sure to represent the angles as accurately as possible in the drawing.
o Butadiene: This was done in lecture and is one of the TD exercises. We went through it very slowly. What geometrical information comes from VSEPR? Draw the sigma-skeleton. Draw the pi-system. We will continue with more about the pi-system tomorrow.

COVERED:
We continued butadiene. In particular, I went back to ethylene and discussed the sigma-skeleton and the pi-system. Then we went to butadiene, quickly reviewed the sigma-skeleton and then carefully went through the pi-system. The connection was made with the particle-in-the-box and with resonance structures.
4.3.5.2. Valence-Bond Theory (AO Hybridization)
4.3.5.2.a. H2C=CH-CCH, H2C=CH-CH3, H2C=C=CH2
I will not be doing 4.3.5.2.b. H3C-O-CH=CH-CN with this group for reasons of lack of time. We will not be doing the question on Color and Electronic Structure

DAY, DATE, TIME, ROOM: Fri. 2021.09.24 8h00-9h30 DLST-TD D004
COVERED:
We had to start with some gentle clarification as students seemed to be lost: some started to prepare the Xstal TD2... I thought things were clear, but it seems it was not.
I also repeated they were expected to be acitve and work before coming.
Generally, I'm a bit worried that coming back to a normal organization after the covid time is a bit difficult for some of them.
Anyway, we did the following (together, actually):
- Section 4.1 Units:
1 dimensional analysis
2 Expressing Composed Units in Terms of Fundamental Units
3. Fermi Estimations
- Section 4.2.1 Review analysis:
Particles and isotope concepts.
the calculation of quantity of matter and elemental analysis will be corrected next week (I asked them to work on it, but it's not a homework).
They were overall active and did not hesitate to participate.

This morning, we could continue the exercises started yesterday, we did
4.2.2: exercises 3 (photoelectric effect II)
exercise 4 (compton effect, which is nice to insist on the good use of conservation of energy).
exercise 5 about Hydrogen Atom and Line Spectra.
Some students seem to work faster than the pace I "impose" but I sometimes realize they don't fully finish the exercise or switch to the next if they don'tmanage to solve it easily...
All in all, correcting was usefull to every body.
Not all studets showed up (16 present) but they were all working seriously. Again they seem to be motivated and interested, even if there's some need for improvement of their working methods...

We did exercises 4.2.2.9 and 4.2.2.10.
We then started talking about quantum mechanics. Before starting the first exercise, we discussed about the concept of wave function, operator, eigenvalue, eignstate, density and Schrödinger equation. I usually present a wave function as a "tool" that will be used to determine some properties.
I also repesented (again) the atomic orbitals and the associated quantum numbers.
Some students had some difficulties to make the relation between equation and shape of the function.
However, we only worked on the two first questions. (a, b and c, unfinished)... To be continued tomorrow morning.

COVERED:
We finished the part about the atomic orbitals and quantum number by doing exercise 4.2.3.3 Quantum numbers. I think students have become familiar witht he concepts.
We briefly talked about the spin and the Pauli exclusion principle.
I also spent time talking about how to switch from the 1-electron problem to the many electron atom and the consequence tha E now depends on (n,l) instead of n only (I fact, I indirectly introduced the orbital azpproximation )
That way, I could formally introduce the Madelung's rule and explain the Aufbau principle and talk about the Hund's rule.

TD: 13
DAY, DATE, TIME, ROOM: Fri. 2021.11.19 8h00-9h30 DLST-TD D004
COVERED:
We finished the exercises about Lewis dot structures (4.3.5) and I also corrected exercise 4.3.6 about reactivity, especially introducing the "half-arrow" for the single electron "move".
I then spend the last 30min. lecturing about VSEPR and asking students to read chapter 20 of the lecture notes.

DAY, DATE, TIME, ROOM: Thu. 2021.11.25 11h30-13h00 ALPILLES 1 SALLE TD A 27
COVERED:
For 14th TD with PCM students, we worked on the VSEPR method:
We did the exercise 4.3.2.1 on geometry of different molecules and I switch to dipole and did a bit of (improvised) lecture on the topic.

TD: 15
DAY, DATE, TIME, ROOM: Fri. 2021.11.26 8h00-9h30 DLST-TD D004
COVERED:
We finished the exercises about the VSEPR method, especially doing exercise 4.3.2.3 about dipoles and 4.3.3.3 about As-halogenes compounds.
We then switched to MO theory, and did 20min. of discussion about the formation of MO's on the basis of 2 AO's, illustrated by the case of H2. I also talked about the notion of overlap. We will start the exercises about that part on next Thursday.

TD: 16
DAY, DATE, TIME, ROOM: Thu. 2021.12.02 11h30-13h00 ALPILLES 1 SALLE TD A 27
COVERED:
We worked on the MO theory with exercises 4.3.4.1 (OVerlap) and 4.3.4.2 (H2 species) and 4.3.4.3 about F2 and associated ions. It was rather n "exercise-based" lecture (kind of) duiring which I spoke a lot, but I think students need to have explantation and be kind of "guided" as I feel this part is very new and thus difficult for them. I also used the Orbimol website to show the actual shape of MO's coming from calculation.

TD: 17
DAY, DATE, TIME, ROOM: Fri. 2021.12.03 8h00-9h30 DLST-TD D004
COVERED:
We went on working on MO theory and spent time on the homonuclear diatomic molecules of the 1st row (4.3.4.4). I showed the exchange of order between \sigma_z and \pi orbitals when switching from O2 to N2. I also tried to link the MO diagram with Lewis structure, purposely showing there's not always a one-to-one easy relation between the two (especially for O2, C2 and B2 e.g.).
We skipped exercise 4.3.4.5 about Second-Row Homonuclear Diatomics. I just told them to look at it at home and that the building was analogue to the one of Be2, B2 and C2, respectively.
We then worked (essentially together) on exercise 4.3.4.6 about hydrofluoric acid. I did it a bit differently: instead of completing the diagram, we built it, starting from the AO basis set, that we split, considering the symmetry and then we made the approximation of a non-interacting 2s AO. We used that to rebuild the diagram and represent the MO's and compared it to the Lewis Dot structure.
I finally made a small review speech about VB: recombination of AO's for each of the sp^[1-3] configuration, giving the examples for C2H4, C2H2 and quickly talking about the planarity of butadiene.

COVERED: metallic crystals
Today, was the first TP in Xstal structure with the PCM-int students and also the 1st time I could meet them all.
They overall managed to finish the different parts of the TP. I had to make few reminders about the notions of lattice and centering plus some explanation about the physicist's vs chemist's point of view. I think most of them managed to get it well.
I asked for the report before next Monday (that way, I give them the whole weekend to work on it) but I insisted that "the sooner the better" for everything to be fresh in their mind.

COVERED: Study of Interstitial Sites
We did Xstal lab 2. I think they all managed to treat the questions. All students showed up.
I think it’s a good practice to work on interstitial sites, including those of BCC structure that are sometimes hard to visualize (and show 😃)
We therefore started by correcting quickly the preparatory exercises.
We then worked on the interstitial sites of the SC, FCC and finally BCC structures.

We then divided the group into two subgroups in preparation for next week's TP. This took quite a while. I decided that we might as well chose the two class representatives for the réunions pédagogiques. So we did this as well.

COVERED: metallic crystals
This TP proceeded pretty much as in past years. However two students were absent without excuse, which is worrisome as labs are required to pass the course! Some of the usual questions came up: (1) What are the distance units used in CRISTAL 2000 ? (failure to specify units is a program flaw), (2) What is the difference between the "Chemists and Crystallographers" and the "Solid-State Physicists and Spectroscopists" points of view? (so this was another chance to explain!), (3) What does it mean to speak about the direction in which atoms are tangent? (yes, it is weird crystallography jargon), and (4) Do we have to fill out the tables as well as answer the questions? (the tables are there to help students to complete all the questions). I was careful to go through the very important gold-copper alloy question with all the students!

Only the models are needed, but the students used the computers and the internet to access the lab document and sometimes to search for images to help them draw some of the intersitial sites. I worked out Ri/R for the Td interstitial site of FCC on the board. The students worked out Ri/R for the cubic interstitial site of the SC lattice and for the Oh interstitial sites of the FCC and BCC lattices on their own. Most of the students left a few minutes early.

DAY, DATE, TIME, ROOM: Mon. 2021.09.13 15h15-16h45 DLST-TD B011
COVERED:
We did the 1st TD with the PCM students. They all eventually showed up and were quite active. However, I felt them a bit lost, hence I have the feeling that I spoke a little bit too much (If not to say "I spent the whole session talking"...) We went through exercise 1 about SC, BCC and FCC crystal structures, discussed the "chemists&crystallographers" vs "physicist&spectroscopists" point of view. We did exercise 2 very quicky and did the first part of exercice 3 (about the density of Ta). I asked them to do the part about Fe and the internet research. I also constituted the two subgroups for next week's TP by splitting the list in two.

On Monday afternoon, we did th 1st Xstal TP with the PCM students who all showed up.
All the students managed to finish the work in time in both groups: we could talk again about the concepts of lattice, basis and coordinate systems (crystallographers vs spectroscopists pov).
I think the new format allows students to properly answer the questions without hurrying too much.
I asked the students to send me their lab report before Friday night in any format (word/opendocument/latex/pdf/picture).
However I had the feeling that some were very unprepared, I thus gently re-explained that they had to work before coming.

Both groups managed to cover all the questions in time, some even leaving earlier as I alllowed them if they had finished. Things went quite well. Most students had worked before coming and it seems this TP has been very useful in understanding the interstitial sites. I think this has been a "reinssuring" time during which they managed to do things by themselves with just small hints from me.

COVERED:
I was able to connect my computer to the projector with the HDMI connector. All students showed up (except one who was excused in advance.) The room is nice but the back rows are (it seems to me) too far from the blackboard at the front of the class. I projected the Xtal TD 1 exercises at the front of the room. Students either used this or viewed the exercises on their own portable computer or smart phone. I had students come to work problems at the board but I just explained for other problems. We did:
Ex. 1. SC, BCC, FCC --- sketching, system centering, atom count, basis atoms in "chemists' and crystallographers' point of view", and generating vectors in "solid-state physicists' and spectroscopists' point of view". The important thing about the latter is to realize that there is always a primitive unit cell.
Ex. 2. Volume of a sphere, 2D and 3D Pythagorean theorems.
Ex. 3 (a). Ta has a BCC unit cell and r = 145 pm. Find the lattice parameter a and the density rho.
The following is homework which should be turned in electronically by the end of this Friday 18 September (Discord is an excellent way to do this):
Ex. 3 (b). gamma-Fe has an FCC lattice and a density of 7.9 g/cm3. Find a and r.

COVERED:
This went fairly smoothly. There were recurrant questions regarding the difference between the "chemists and crystallographers point of view" and the "solid-state physicists and spectroscopists point of view." These concepts take time to understand but I think the good progress was made. One thing that I did differently for this group was to have several of the students construct a BCC lattice from each of the two points of view:
"Chemists and crystallographers": Chose Cubic P. Introduce explicitly 2 basis atoms.
"Solid-state physicists and spectroscopists": Chose Cubic I. There is only one basis atom. Then I showed them my course notes with the generating vectors actually used by the program.
I made sure to show all the students the AuCu3 example and to carefully talk about why the Bravais lattice is P and not F.

COVERED:
Both subgroups (a and b) did the same thing. We put the emphasis on going from the physical models of the crystal and identifying
(i) the Bravais lattice and (ii) a basis
so that the crystal structure may be entered into and studied with the CRISTAL2000 program. I told the students not to worry about the distinction between the physicists and chemists point of view. The ZnS structure proved to be a particularly good learning experience as seeing that both the Zn2+ and S2- ions have FCC sublattices does not become fully evident until CRISTAL2000 is used. There are some discrepencies (apparently small) between the ionic radii given in the Xtal ''handout'' and in the CRISTAL2000 database. At least one student got to the final table and was trying to figure out how CaF2 fits in. Many students prepared write-ups, even in electronic form. (Is this the result of lockdowns and distance learning?) I had told the students not to turn this in but that I would send them my answers to various questions in the Xtal TP. Instead, their grade for Xtal TP 2 is to be based on their answers to a ''take-home quiz'' that I sent to them and which is due electronically by midnight on Friday.

COVERED:
The new PCs allowed us to have one student per computer. I had a fair number of questions from this group. There was a lot of confusion about the "chemists and crystallographers point of view" versus the "solid-state physicists and spectroscopists point of view." I am convinced that they think it is harder than it really is. I took time to explain the Bravais lattice and basis for the Cu-Au alloy example in some detail. I hope that this will help them a lot when we do TP 2 on the ionic crystals.
The write-ups have come flowing in much faster than I can grade them. In fact, I must design a simplified grading scheme for next year because I am spending far too much time grading each write-up this year.

Once again only a few students got to the final table and so were really able to understand the radius ratio rule. It would be wonderful if all students could get this far but it does not seem possible, so that the main thing that everyone learns is about Bravais lattices and bases (if they did not learn it already) and only a few go on to use the lab to deepen their knowledge of the radius ratio rule.

They seemed quite interested. This was my first "TD" with students wearing masks: this is a bit puzzling as I like to see how they react. It definetely makes the communication more difficult and students less prone to ask questions, I think. Hopefuly we will adapt quickly.

2015-2016. This year Denis Magero replaced Emanuela Di Cola, so we were able to maintain our teaching team at 3 people. I was able to integrate youtube videos more into my teaching. I am running out of space on this web site to upload things and so have increasingly to delete things.
2014-2015. Teaching evaluation file CHEM110_evaluation_enseignement_2014_2015.pdf below. This year one extra TD was added to the xstal teaching but one TD was subtracted from the regular teaching. There was also one week fewer before the midterm which I think upset our planning a bit and helped in allowing the lectures to get a bit behind the discussion sections. Emanuela Di Cola joined our teaching team so that we have 3 people involved in teaching CHI 110 Int this year.
2013-2014. Teaching evaluation file CHEM110_evaluation_enseignement_2013_2014.pdf below. CHI 110 has been reorganized since last year and so there has been a lot of adjustments for us to make. For example, the main course tutorial corrections have been redone. The xstal corrections have been created. Etc. Hopefully things will be a bit easier next semester. There was some unfortunate confusion during the first week when half of the students went to courses taught in French because they did not know that the course was already being taught in English. The midterm also seemed radically different from the midterms of previous years and from what the students thought was expected of them based upon the lecture and discussion sections. The xstal labs seem too rushed. One comment that strikes me as odd is the criticism that the textbook (Atkins and Jones) chosen for the course is not concise enough. I think this expects the different expectations of French and English students regarding the purpose of a textbook. For many English students, the lecture gives the highlights of the subject while the textbook is able to go over the subject in a more lengthy, more detailed way.
2012-2013. We lost a few students in the first week --- either because taking the course in English seemed to challenging or (in the case of one bilingual student) because it was not interesting to follow a course in English from Francophones (criticism not limited to CHI 110 English but to other courses in BIO-INT). This is the first year that we are doing labs also in English. I have noticed that there is more of a tendency to use French as well as English in the labs than in discussion section or lecture. The lab in English seems to be appreciated. I was also pleasantly surprised by how many students found the recommended textbook to be helpful.
2011-2012. This is the first year that this lecture is offered in English. The initial idea was to follow an English (American) textbook as closely as possible. This proved too much for me this first year. Instead I followed my French notes which I managed to translate into English (except for the figures), though I was surprised how hard this actually turned out to be. (You see, I know these subjects in English, but I have done much of my teaching of these subjects in French. It seems that I learned much extra vocabulary when teaching that I had a little difficulty translating into English.) I was away a lot and am deeply grateful to my co-teacher, Yohann Moreau, for his support and to Richard Garcia and Bhaarathi Natarajan for stepping in and giving me a hand when I need it. Among the difficulties encountered this first year were (i) the filthy nature of the lecture room black board and erasers which often made the board close to illegible and (ii) the fact that the lab was taught in French and the students had difficulty relating the vocabulary in lab to the vocabulary used in lecture. An objective that I would like to make for next year is to base the course more directly on the textbook chosen for the course and available in the science library.

When English Wasn't Always a Choice
When English Wasn't Always a Choice
There was a time before the Quiet Revolution of the 1960s that French Canadians were all too often treated as inferior by English Canadians. Michèle Lalonde expressed all the anger of French Canadians of that time in her powerful bilingual poem of 1968 called Speak White (film.) See the wikipedia entry for a discussion of the meaning of speak white.
