Determine the order of stability of the following resonating structure.

Options

  1. Ai > ii > iii
  2. Biii > ii > i
  3. Ci > iii > ii
  4. Dii > i > iii

Correct answer

A. i > ii > iii

Step-by-step solution

Charge separation reduces the stability of the resonating structures. If charge separation exists, the structure with opposite charges closer is more stable. So, i is most stable followed by ii and iii
