Unit 3: Intermolecular Forces and Properties

Goals of Unit 3 Include:

• Performing calculations using wavelength, frequency, energy, and moles of electrons

• Identifying the types of Intermolecular Forces (IMFs) present in substances and mixtures

  • If liquids, using the IMFs of mixtures to determine whether the substances will dissolve AND using the IMFs to explain how chromatography separates the mixture

  • If solid, using the IMFs or other forces present to determine the type of solid

• Using the IMFs present to determine or predict properties of solids, liquids, and gases

• Explaining gas behavior in terms of Kinetic Molecular Theory, Ideal Gas Law, and Deviations from Ideal Gas Behavior

Unit 3 Lecture Videos:

1. Introduction to Light (Professor Dave!)

2. Fundamental relationships between wavelength, frequency, and energy (not me)

3. Calculations involving wavelength, frequency, and the energy of photons in chemistry (not me but very very very good)

4. Types of IMFs

5. Effects of IMFs

6. States of Matter (Ms. Barkume)

7. Kinetic Molecular Theory

8. Gas Behavior Review, Ideal Gas Law (Ms. Barkume)

9. Units of Pressure (Dr. English)

10. Molar Mass of Gases with PV=nRT

11. Deviations to Ideal Gas Behavior

12. Representations of Solutions (Ms. Barkume)

13. Solubility
