Question: In Exercise 65 in Chapter 13 the Lewis structures for
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).
