Chapter 6, Problem 4E

Consider the molecule 1-bromo-2-methylbutane. ${\text{C}}_{\text{3}}$ and ${\text{C}}_{\text{4}}$ should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the ${\text{C}}_{\text{1}}—{\text{C}}_{\text{2}}$ bond...
a. The lowest potential energy conformation.
b. The highest potential energy staggered conformation.
