Question

Which of the following resonating structure is the most stable?

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

In resonance structures, the most stable structure has minimal charge separation and the negative charge is placed on the most electronegative atom.

Answer 1

The Correct Option is A

Step 1: Understanding resonance structures.
In resonance structures, the most stable structure is the one with the least charge separation and with negative charges on more electronegative atoms. The structure in option (1) has the most stable charge distribution, where the nitrogen atom holds the negative charge and the carbon atoms bear partial positive charges.
Step 2: Conclusion.
The correct answer is (1) as it represents the most stable resonating structure.
