Post Lab Questions:

1. Describe the underlying principle of VSEPR theory.

2. Explain why two compounds with the same generic formula, NH3 and BH3, have different geometries and different shapes.

3. Why are the structures of H2S and H2O so similar? Why are the structures of O3and SO2 so different?

4. Although PH3 and BH3 both contain bonds with similar polarity, one molecule is polar while the other molecule is nonpolar. Explain.

5. Write a detailed procedure for converting a chemical formula into a Lewis structure and how to determine the shape, and polarity from this Lewis structure.

Plz you can number the answes that will be very helpful. Thanks

Hydrocarbon Lab Post-Question: Two of the compounds in this experiment had similar odors, yet their molecular structures are very different. Comment on factors at the molecular level that may be involved in the mechanism of smell. (Assume that a nerve impulse to the olfactory center of the brain is initiated by interaction of molecules, in this case the hydrocarbons, with a receptor in the nose.)
