resonance hybrid
the structure that results when a chemical entity exhibits resonance (def. 2), such as occurs by the sharing of one or more electrons over several bonds. It has a lower energy than any of the possible formal nonresonance contributing structures, giving additional stability of which the so-called resonance energyis a measure. A classic example is carbon dioxide, which may be represented by the Lewis formulafor each as
