In Exercise 65 in Chapter 13, the Lewis structures for benzene (C6H6) were drawn. Using one of the Lewis structures, estimate ΔH°f for C6H6(g) using bond energies and given the standard enthalpy of formation of C(g) is 717 kJ/ mol. The experimental ΔH°f value for C6H6(g) is 83 kJ/ mol. Explain the discrepancy between the experimental value and the calculated ΔH°f value for C6H6(g).
