Question: Use average bond enthalpies (Table 8.4) to estimate for the atomization of benzene, C6H6: C6H6 (g) 6C (g) + 6 H (g) Compare the

Use average bond enthalpies (Table 8.4) to estimate for the atomization of benzene, C6H6:
C6H6 (g) → 6C (g) + 6 H (g)
Compare the value to that obtained by using ΔHof data given in Appendix C and Hess's law. To what do you attribute the large discrepancy in the two values?
