JEE Main Chemistry question

Benzene is a resonance hybrid mainly of two Kekulé structures. Hence

(A)Half of the benzene molecules in a sample correspond to one structure, and half to the second
(B)At low temperature, benzene can be separated into the two individual Kekulé structures
(C)The two structures make equal contributions to the one real resonance hybridCorrect
(D)An individual benzene molecule continually changes back and forth between the two structures

Answer: (C)

Solution

Resonance theory describes a single, real, time-independent molecule as a weighted blend ("hybrid") of hypothetical canonical structures; benzene's
