Which statement about resonance hybrids is true?

A.The hybrid is more stable than any single contributing structure

B.The hybrid is the average energy of the structures

C.Each structure exists for a measurable time

D.Resonance weakens the molecule's bonds

Explanation

Core Concept

Delocalizing electrons across several positions lowers the molecule's energy. That extra stability is called resonance stabilization — the hybrid beats every individual Lewis form.

Correct Answer

AThe hybrid is more stable than any single contributing structure
