Post Lab Questions

1 Why did H2O H2S have the same shape polarity?

2 Why wasn't C2H2 polar if it has a "divisible" axis?

3 Why wasn't CCl4 polar even though ALL of its bonds were polar?

4 Why was BI3 trigonal planar NOT pyramidal?

5 Which molecule's shape polarity results were the most surprising WHY?
