Objectives:

1. Students will be able to correctly determine the 3-Dimensional Shape of a molecule by analyzing its Lewis Structure and consulting the VSEPR chart.

2. Students will be able to determine if a molecule is polar or non-polar based on its molecular geometry.

Warm-Up:

1. What is polarity?  What are the two causes leading to polarity?

2. Would the following molecules be polar or non-polar?  Why?      (hint- remember to start with a correctly drawn Lewis Structure)

                        NH₄⁺                HCl                    PI₃
