Heat of dissociation of benzene into elements is 5335 kJ/mol. The bond enthalpies of C-C, C=C and C-H bonds are 347.3, 615 and 416.2 kJ respectively. Resonance energy of benzene is

Answer: (C)

Solution

Expected (Kekulé) dissociation energy $=3(C{-}C)+3(C{=}C)+6(C{-}H) = 3(347.3)+3(615)+6(416.2) =
