Resonance phenomenon is generally involved when single valence bond structure could not represent the actual structure of the molecules or species. Based on the actual bond lengths, bond energies etc, of the molecules or species, resonance phenomenon will help to achieve at the correct structure of the species or molecules.
Which of the following is correct

Options

A. Reasonance hybrid is stabler than connonical structures
B. C annonical structures are not real structures of the molecules
C. Resonance structures differ in the distribution of electrons only
D. All the above

Answer

D

Explanation

a) Reasonance hybrid is stabler than connonical structures
b) Cannonical structures are not real structures of the molecules
c) Resonance structurs differ in the distribution of electrons only
