Question

Which of the following statements about the conformation shown below are true? 
A) The ethyl and methyl groups are both axial. 
B) All three alkyl substituents are equatorial. 
C) The ethyl group is axial and the methyl group is equatorial. 
D) The ethyl and methyl groups are both equatorial and the propyl group is axial.

Quizplus · Accepted Answer

The ethyl group is clearly shown as axial (pointing straight up or down) while the methyl group is shown as equatorial (projecting outward from the ring). The propyl group is not explicitly labeled or shown in the conformation pictured. Therefore, C is the only statement that can be verified as true based on the given information.
