Question

Compare the stability of the given resonating structures :

• A. Structure A is less stable than structure B
• B. Structure A is more stable than structure B
• C. Structure A and structure B are equally stable
• D. Cannot comment about stability.

Answer 1

The correct option is B Structure A is more stable than structure B

A non polar resonating structure is more stable than a polar resonating structure (having charges).
Structure B is a polar structure with more formal charges whereas structure A is a non polar structure .
So, structure A is more stable than B
