Which of the following statements is not correct for resonance strucuture?

Options

A. None of the individual resonace structures explians all the characteristics of the actual molecule.
B. The resonance hybrid has equal contribution from all the resonating strucuture.
C. The different resonace structure of a molecule should have the same number of unpaired electrons.
D. The different resonating structures of a molecule have fixed arrangements of atomic nuclei.

Answer

B

Explanation

Equivalent resonance structure make equal contributions to the hybrid while structure that are not equivalent do not make equal contributions.
