Experimentally (and consistent with the calculated bond lengths in Model 1), we find that all six $mathrm{C}-mathrm{C}$ bond lengths in benzene have the same bond length, $139 mathrm{pm}$. Is this fact more consistent with the bond orders predicted by the Lewis structure or with the calculated bond orders? [Hint: refer to your answer for CTQ 4.]
