Chemical Bonding, Electronegativity and Polarity, VSEPR Theory for Molecular Geometry

Read Chapters 8 and 9 (except for MO theory) doing the example problems.

In Chapter 8 take “bond enthalpies” to mean “bond energies” (for now “bond energy” means the minimum energy necessary to pull atoms apart and break a bond). Also don’t worry about the Born-Haber cycle yet. And in Chapter 9 ignore section 9.7 (pp 373-385) on molecular orbitals (at least for now).

Ch10 (pp437-441) 69-85 odd, 102,103




Read and re-read Chapter 5 on thermochemistry doing the example problems.

Make sure you understand the difference between “heat”, a form of energy transfer, and “temperature”, a measurable property (and a state function!) related to average kinetic energy of molecules in a “system”. Precise use of words is a huge part of thermochemistry! Use the “Summary and Key Terms” at the end of the chaper (p203).
