Question
Which of the following has two equatorial alkyl substituents in its most stable conformation?
Correct Answer
Option C is the correct answer.
Detailed Explanation
cis-1,3-diethylcyclohexane has both ethyl groups equatorial in its most stable conformation (diequatorial). In cis-1,2 and cis-1,4 isomers, one substituent is axial and one is equatorial. 1,1-dimethylcyclohexane has both groups on the same carbon.
Hint
Which cis-1,3-disubstituted cyclohexane has both substituents equatorial?
