Vedclass · Answer

(C) The heat of hydrogenation $(\Delta H_{hyd})$ is inversely proportional to the stability of the alkene. $1$. More substituted alkenes are more stable,hence they have lower $\Delta H_{hyd}$. $2$. Trans-alkenes are more stable than cis-alkenes,hence cis-alkenes have higher $\Delta H_{hyd}$. $3$. Increased ring strain leads to higher $\Delta H_{hyd}$. In option $C$,the first molecule is a highly strained bicyclic alkene (bridgehead double bond in a small ring system),which makes it significantly less stable than the isomer in the second part of the option. Therefore,the first molecule has a higher heat of hydrogenation,making the order $C$ correct.

Identify the correct order of heat of hydrogenation.
