What is Resonance Hybrid?
A resonance hybrid is the actual structure of a molecule or polyatomic ion that cannot be represented adequately by a single Lewis structure. It is the weighted average of all contributing resonance structures (canonical structures). The resonance hybrid has delocalized electrons and bond orders intermediate between single and double bonds. The actual molecule is more stable (lower energy) than any single resonance structure — this stabilization is resonance energy.
