The stability order of the following resonance structures is

Options

  1. AIII < II < I
  2. BII > I > III
  3. CII < I < III
  4. DII > III > I

Correct answer

A. III < II < I

Step-by-step solution

(I) A neutral structure, which has complete octet is most stable resonating structure. Since, more electronegative atom consist negative charge. Hence, (II) is more stable as compared to (III). Stability order III < II < I Hence, option (a) is correct.
