Question:medium
Which of the following conditions should be met while writing the canonical structures of a resonance hybrid ?
A. The magnitude of resonance energy should be low and the hybrid will be more stable
B. The number of unpaired electrons should be same in all the canonical forms
C. Canonical forms where similar charges develop on vicinal atoms are highly significant forms
D. The positions of the nuclei of each canonical form and the hybrid must remain same
E. Only a pair of electrons should be shifted in writing the canonical forms
Choose the correct answer from the options given below :

Show Hint
The absolute rules of resonance: 1. NEVER move atoms (nuclei). 2. NEVER exceed the octet rule for 2nd-row elements (C, N, O, F). 3. Conserve the total net charge and the number of unpaired electrons.
