5. A Lewis dot structure for benzene, C 6 H 6 would give two equivalent resonance structures for this cyclic molecule with alternating single and double bonds A combined VB and MO picture for the bonding of the carbon atoms in benzene would be a. 3 " (C2p–C2p) bonds between each C atom b. 2 " (Csp 3 –Csp 3 ) bonds between each C atom, and 1 # MO delocalized over the C's
