The cyloalkane having the lowest heat of combusion per `CH_(2)` group

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
Cyclohexane is virtually strain-free. Hence, the heat of combustion per `CH_2` is the same as for n-alkanes (157.4 k cal). The increase in heat of combustion for the smaller rings is due to increase in angle-strain.
