This week we will get started with cirriclium! The stuff we learn is HERE on my website, and due dates for the WHOLE UNIT are on Schoology.
These videos are NOT required, but do offer a different perspective on the topic if that helps!
Tyler DeWitt - a very details walkthrough of how VSPER Theory works as well as a discussion of how each shape makes sense in terms of the rules of the theory. Very details, yet still very easy to follow!
Tyler DeWitt - More from Tyler! This time he has an example problem for determining the VSEPR shape from a LDS. He does a great job of discussing some key questions you can ask yourself for each problem to help get you to the correct shape. Very helpful!
OldSite Vanden Bout - A similar discussion that focuses more on the shapes themselves. Great animations and visuals to make those shapes easier to visualize.
The links below are sites with written descriptions of this content. Some prefer to learn from reading rather than watching. If that helps you these resources can be useful!
Byjus's - This site is a test prep site for students taking entrance exams for college in India. Very well organized discussion of VSEPR theory that goes a little beyond what we do in class. There is a great chart of the different shapes if you prefer that to mine!
Lumen Learning - Straightforward and detailed. Another clear discussion of VSPER theory and how to use it! Lumen provides in general great online textbook alternatives. You can use this book for ANY topic in chem!
Resources
VSPER Chart - This chart list all of the VSEPR shapes that you are responsible for identifying in practice labs, and tests. There are certainly more shapes out there, but these are the most common and relevant to our work in class. You MUST have access to a copy of this doc for ALL class work!
COMPLETE VSERP Chart - Similar information to the chart above, but this includes ALL the possible VSEPR shapes. This is generally more information than is needed for our class, but if you have a LDS that doesn't seem to match up to one of our more common shapes, here is a place to look!
MolView - This is an online molecular model kit you can use to first write out a LDS of your compound and then translate it into a 3D VSEPR model. Should work really well, but maybe not a 100% replacement for a real kit you can hold in your hand. Glad to hear feedback on how useful this is! Directions and vids are available on the start page to help you learn how to use the interface!
Class Practice
Complete the practice docs below. Complete BOTH for the Practice this section.
You will practice your skills with LDS's and VSEPR Theory by working with molecular model kits. This kits allow you to build models of atoms that you can hold in your hand, making visualizing the results of VSEPR Theory MUCH easier. Make sure to learn how the kits work, because you can use them on tests!!
To prove mastery of this topic you will need to take a quiz on Schoology. Here are the guidelines:
You must show me all the completed work for this section BEFORE you you can start attempts on this quiz.
You CANNOT use any notes, practice, or prior quiz attempts to help you complete the quiz. This quiz is CLOSED NOTES!
You CANNOT work with others on the quiz.
You CAN use ANY class resources like a calculator, your periodic table, or any other reference materials. These are often lined on the quiz itself.
You should also have you Nomenclature Summary Doc you made for ht lab activity in this section.
You have 5 attempts to pass this quiz.
Do NOT take multiple attempts at once if you are not sure why you got questions wrong.
Do NOT take another attempt if you got the same grade again.
DO see Mr. Kiefer for help and to go over previous quiz attempts.
You should only need 2-3 tries for each quiz. If it takes more than that you should be reaching out for help!
