Question:

The correct order of heat of combustion for following alkadienes is:

1. $(\mathrm{A})<(\mathrm{B})<(\mathrm{C})$

2. (A) $<(\mathrm{C})<(\mathrm{B})$

3. $(\mathrm{C})<(\mathrm{B})<(\mathrm{A})$

4. $(\mathrm{B})<(\mathrm{C})<(\mathrm{A})$

Correct Option: 1

Solution:

In isomers of hydrocarbon heat of combustion is inversely proportional to the stability.

Stability order: $A>B>C$

Order of heat of combustion: $A<B<C$
