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.
