The order of relative stability of the contributing structure is:
Choose the correct answer from the options given below:
Choose the correct answer from the options given below:
- $I >II >III$
- $II >I >III$
- $I = II = III$
- $III >II >I$
The Correct Option is A
Solution and Explanation
Structure I is the most stable because it is a neutral resonating structure. In general, neutral structures are more stable compared to charged structures.
Structure II is less stable than I because it involves a positive charge on a less electronegative atom compared to structure III. However, it is more stable than III because the negative charge in III is on a carbon atom, making it the least stable due to charge separation.
Structure III is the least stable among the three due to the presence of a negative charge on carbon and overall charge separation, making it highly unstable.
The Correct answer is: \(I >II >III\)
