- Consider the molecule 1-bromo-2-methylbutane. C3 and C4 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 C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.a model of cyclohexane in a chair conformation, and explain why the names “axial” and“equatorial’ are appropriate.Two conformations of cis-l, 3-dimethylcyclobutane are shown. What is the difference between them, and which do you think is likely to be more stable?
