Vedclass · Accepted Answer

gives off $152 \, kJ/mol$ less heat

Vedclass · Answer

(D) The hydrogenation of a hypothetical $1,3,5-$cyclohexatriene would release approximately $3 	imes 120 \, kJ/mol = 360 \, kJ/mol$ of energy.Benzene is stabilized by resonance,having a resonance energy of approximately $152 \, kJ/mol$.Therefore,the actual heat released during the hydrogenation of benzene is $360 \, kJ/mol - 152 \, kJ/mol = 208 \, kJ/mol$.Since benzene releases $208 \, kJ/mol$ and the hypothetical cyclohexatriene would release $360 \, kJ/mol$,benzene gives off $152 \, kJ/mol$ less heat than the hypothetical cyclohexatriene.

When comparing the hydrogenation of benzene with that of a hypothetical $1,3,5-$cyclohexatriene,benzene .................... than the cyclohexatriene.
