In the Lewis structure of ozone O₃, what does the pair of equivalent structures indicate?
A.Resonance
B.The molecule alternates between forms rapidly
C.One oxygen violates the octet rule
D.The molecule is ionic
Explanation
Core Concept
Two valid structures differ only in which O–O bond is double. Neither is real; the molecule is a hybrid with both bonds equal — longer than a double bond, shorter than a single.
Correct Answer
AResonance
