Among the following the most stable compound is

A

cis -1,2- cyclohexanediol

B

trans -1, 2- cyclohexanediol

C

cis -1, 3- cyclohexanediol

D

trans -1, 3- cyclohexanediol

Text Solution

Verified by Experts

The correct Answer is:
D
Trans configuration is more stable than cis configuration because in cis-configuration the H groups are thrown closely enough together to cause crowding or repulsion. Again between 1,2-and 1,3-configurations, in 1-3, the OH groups are placed further apart to minimise the repulsion. Hence, more stable is 1,3-configuration
