1. Draw the Newman projections for ethane and the C1-C2 bond of propane.

2. Which of the projection in #1 would have the highest energy? Why?

3. A chiral molecule requires a stereogenic center. What must be true about a carbon atom in a molecule for it to be a stereogenic center?

4. Based on the answer to #3, Draw the smallest acyclic chiral alkane and using wedges, show it in the S configuration.
