Vedclass · Answer

(C) The heat of hydrogenation is inversely proportional to the stability of the alkene. More substituted alkenes are more stable. Compound $I$ is a tetrasubstituted alkene (most stable). Compound $III$ is a trisubstituted alkene. Compound $II$ is a disubstituted alkene (least stable). Therefore,the stability order is $I > III > II$. Consequently,the order of heat of hydrogenation is $II > III > I$.

Which of the following orders is correct for the heat of hydrogenation of these compounds?
