Question
When comparing the Heat of Combustion (HOC) of structural isomers, the primary determining factor is the internal stability of the isomer. For the $C_6H_{12}$ isomers, which will have the HIGHEST Heat of Combustion?
Answer: B
💡 Solution & Explanation
Unlike HOH, HOC burns the entire skeleton. For isomers (same C count), Highest HOC = Least Stable Alkene. 1-Hexene has only 2 $\alpha$ -hydrogens, making it the least stable of the group, thus releasing the maximum energy upon complete combustion.
