JEE Mains · Chemistry · STD 11 - 8.4. Organic chemistry reaction mechanism
The correct order of heat of combustion for following alkadienes is

- A \((a) < (b) < (c)\)
- B \((b) < (c) < (a)\)
- C \((c) < (b) < (a)\)
- D \((a) < (c) < (b)\)
Answer & Solution
Correct Answer
(A) \((a) < (b) < (c)\)
Step-by-step Solution
Detailed explanation
Generally trans is more stable then cis form Heat of combustion (HOC) \(\propto \frac{1}{\text { Stability }}\) Stability : \(a>b>c\) \(\mathrm{HOC}: \mathrm{c}>\mathrm{b}>\mathrm{a}\)
