Benzene is actually a resonance hybrid between the two Kekule structures. The C-C bond lengths in benzene are shorter than typical single-bond lengths,yet longer than typical double-bond lengths (bond order 1.5). Benzene's resonance can be represented by drawing a circle inside the six-membered ring as a combined representation.
