1. Look at your sketches for the models of methane and dichloromethane.  How are they similar?  (choose one)

1. Same structure

2. Same elements

3. Polarity

4. Same chemical formula

1. Use your data tables to relate symmetry to polarity. Explain the role symmetry plays in polarity.

2. Carbon monoxide is reactive but carbon dioxide is non-reactive.  Explain why.

3. Organic compounds are those that contain carbon.  What percentage of the models you constructed are organic?
