Relative stability of the contributing structures is :
(A)(I) > (III) > (II)
(B)(I) > (II) > (III)✓ Correct
(C)(II) > (I) > (III)
(D)(III) > (II) > (I)
Answer: (B)
Solution
Neutral resonance structures are more stable than charged ones, so (I) (no formal charges) is most stable. Among the charged ones, positive charge on the less electronegative carbon (II) is preferred over on oxygen (III). Order (I) > (II) > (III). Option (2).
