Vedclass · Answer

(D) The canonical forms (or contributing structures) have no real existence.The molecule does not exist for a certain fraction of time in one canonical form.There is no such equilibrium between the canonical forms as we have between tautomeric forms in tautomerism.The molecule as such has a single structure which is the resonance hybrid of the canonical forms and which cannot be depicted by a single $Lewis$ structure.
