Which cycloalkane has the lowest heat of combustion per \(\mathrm{CH}_{2}\) group?
- A cyclopropane
- B cyclobutane
- C cyclopentane
- D cyclohexane
Answer & Solution
Correct Answer
(D) cyclohexane
Step-by-step Solution
Detailed explanation
Cyclohexane has the lowest heat of combustion per \(\mathrm{CH}_{2}\) group. As, stability increase upto 6 membered ring due to decrease in angular strain. Also heat of combustion is measure for chemical stability.
