Solution


Q.

The correct stability order of the following resonance structures of                      [2024]
1 II > I > III  
2 III > II > I  
3 II > III > I  
4 I > II > III  

Ans.

(2)

Neutral resonating structures are more stable than charged resonating structure. Amongst charged resonating structures, those structures which have negative charge on more electronegative atom and positive charge on less electronegative atom are more stable.
