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?

Prashant Kotian · Accepted Answer

Correct answer: B. Unlike HOH, HOC burns the entire skeleton. For isomers (same C count), Highest HOC = Least Stable Alkene. 1-Hexene has only 2 -hydrogens, making it the least stable of the group, thus releasing the maximum energy upon complete combustion.
