Vedclass · Answer

(A) The heat of hydrogenation for one double bond in cyclohexene is $\Delta H = -28.6 \ kcal/mol$.Anthracene has $7$ double bonds that can be hydrogenated.Therefore,the theoretical heat of hydrogenation for anthracene is $7 	imes (-28.6 \ kcal/mol) = -200.2 \ kcal/mol$.The experimental heat of hydrogenation for anthracene is given as $-116.2 \ kcal/mol$.Resonance energy = (Theoretical heat of hydrogenation) $-$ (Experimental heat of hydrogenation)Resonance energy = $(-200.2 \ kcal/mol) - (-116.2 \ kcal/mol) = -84 \ kcal/mol$.The magnitude of the resonance energy is $84 \ kcal/mol$.

Use the following data to answer the question below.
Calculate the resonance energy of anthracene in $kcal/mol$.
