Structures ________, shown below, are resonance structures, and structure ________ is the major contributor to the overall resonance hybrid.

Question

Quizplus · Accepted Answer

Structures 1, 3, and 5 are the resonance structures because they differ only in the location of the double bond and the position of the lone pair on the nitrogen. Structure 3 is the major contributor because it has the least separation of charge, as the negative charge is localized on the oxygen and the positive charge is localized on the nitrogen.
