Question

The order of relative stability of the contributing structure is: CH =CH– C–H I O CH – CH = C – H II O CH – CH = C – H III O Choose the correct answer from the options given below:

(A) I > II > III
(B) II > I > III
(C) I = II = III
(D) III > II > I

Correct answer: A. I > II > III, since neutral resonating structures are more stable than charged resonating structure. II > III, since stability of structure with –ve charge on more electronegative atom is higher.
