Lecture slides – Wed Sept 2

You can download all of the slides (in color) from today’s lecture here.
Judging from the in-class and post-class questions that I’ve received,
electron density surfaces and electrostatic potential maps probably
generated the most confusion. Let me refer you to two sets of ROCO
essays that can help.

If you want to focus on your textbook, today’s lecture addressed the following sections of chapter 1:

  • 1.2 – Classical theories of chemical bonding
  • 1.3 – Structures of covalent compounds
  • 1.4 – Resonance structures

The remaining half of chapter 1 really covers only two topics:

  • quantum mechanical models of atoms (1.5, 1.6, 1.7)
  • quantum mechanical models of molecules (1.8, 1.9)

I plan to cover all
of this on Friday which seems kind of crazy, but the material on atoms
should be review from Chem 101 (waaaay back). Go back and look at your
Chem 101 stuff. I am not going to talk much about atoms or atomic
