The isomer expected to have the greater heat of combustion is to be identified, and the reason for it is to be explained. Concept introduction: If two molecules are isomers of each other, they have precisely the same combustion products. As a result, any difference in the heat of combustion must be attributed to differences in stabilities of the alkenes . The compound with the smallest heat of combustion is most stable. Double bond stability increases as the amount of alkyl substitution increases due to hyperconjugation. Hyperconjugation involves alpha C-H σ bond and π electrons of double bond. As the number of C-H σ bonds next to double bonded carbon atom increases, hyperconjugation increases. Hyperconjugation leads to the stabilization of double bond.
