Which of the following compounds can adopt a chair conformation in which there are no axial methyl groups?

Question

Quizplus · Accepted Answer

DIn a chair conformation of cyclohexane, substituents can occupy either axial or equatorial positions. For a compound to have no axial methyl groups, all methyl groups must be able to adopt equatorial positions simultaneously. In trans-1,2-dimethylcyclohexane (C), the two methyl groups are on opposite sides of the ring, allowing them to both be in equatorial positions in one of the chair conformations. Similarly, in cis-1,3-dimethylcyclohexane (D), the two methyl groups can also both occupy equatorial positions simultaneously in one of the chair conformations.
