1. Do Now
Using what you know about polar bonds, identify the following molecules as mostly polar or mostly non-polar.

2. Aim
How does molecular geometry affect polarity?

3. Solubility as a Test for Polarity
Water and Oil
Insoluble
Water and CTC
Insoluble
Water and Ether
Insoluble
CTC and Ether
Soluble

4. Why isn’t CTC polar?

5. Why isn’t CTC polar?
Polar molecules must be

6. Molecular Geometry: Overview
Four bonds:
Example:
Three Bonds:
Two or one bond(s):

7. Practice time!

8. Your Turn!

9. Checking Out
