Unit 8: Chemical Bonding


This video is from another AP Chem teacher going over Lewis models, formal charges and then discussing VSEPR (Valence Shell Electron Pair Repulsion), which is our next topic. VSEPR is how chemists try to decide the shapes of molecules. These shapes are important in how molecules behave. [|Please watch]

Please view my notes on VSEPR:

The second video is about polarity. Now that you understand molecular shapes, we can use that understanding to determine whether a molecule is polar or nonpolar. [|Please watch]

(I added one extra question (#94) to give you extra practice with more complex molecular shapes)



Unit 11: Solutions (Concentration and Solubility only)
- Skip any parts of problems involving molality or percent by mass. They are no longer part of the AP Chemistry curriculum.

Unit 12: Chemical Kinetics
Assignment 12.2 is quite long, so I split it up into 2 parts. Both require graphical analysis, so we will do these in class.



Unit 13: Equilibrium




Unit 14: Acids and Bases




Unit 15: Applications of Aqueous Equilibria
