Among the following the most stable compound is

Options

A. cis-1,2-cyclohexanediol
B. trans-1,2-cyclohexanediol
C. cis-1,3-cyclohexenediol
D. trans-1,3-cyclohexanediol.

Answer

D

Explanation

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