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

Options

A. Contributing structures are less stable than the resonance hybrid.
B. Contributing structures represent molecules having no real existence.
C. Equivalent resonating structure make the resonance very important.
D. Contributing structure contribute to the resonance hybrid in proportion of their relative energies.

Answer

D

Explanation

Relative contribution of a resonance structure is inversly proportional its energy but directly proportional to its stability. Thus, the lesser the energy and the more stable the sturcutre, the greater is its contribution to the hybrid.
