Freshman Chemistry Guide 9

This study guide contains over 4 hours of recorded lecture topics and example problems that follow the material covered in chapter 10 of the textbook Chemistry, The Molecular Nature of Matter and Change by Silberberg. The topics covered include:

The Lewis dot structures depiction of atoms and their bonding and lone electron pairs in a molecule or ion.
Using resonance and electron delocalization to explain bond properties in compounds with double bonds adjacent to single bonds.
Calculating the formal charge of atoms and using it to select the most important resonance structure in molecules and polyatomic ions.
Exceptions to the octet rule: molecules with a central atom that has an electron deficiency, an odd number of electrons, or an expanded valence shell.
VSEPR: how electron-group repulsions lead to molecular shapes.
The five electron-group arrangements and their associated molecular shapes.
Why multiple bonds and lone pairs can cause deviations from ideal bond angles.
How bond polarities and molecular shape combine to predict molecule polarity.
