Question 51. The order of relative stability of the contributing structure is:

Choose the correct answer from the options given below:
(1) I > II > III
(2) II > I > III
(3) I=II= III
(4) III > II > I
Answer (1)
Explanation:
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.
