Among the following the most stable compound is
Options
- Acis-1,2-cyclohexanediol
- Btrans-1,2-cyclohexanediol
- Ccis-1,3-cyclohexanadiol
- Dtrans-1,3-cyclohexanediol.
Correct answer
D. trans-1,3-cyclohexanediol.
Step-by-step solution
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 1,3configurations, in 1-3, the OH groups are placed further appart to minimise the repulsion. Hence, more stable is 1,3-configuration.
