Correct order of stability of carbanion is:
Correct order of stability of carbanion is:
Show Hint
Aromatic carbanions are the most stable, while anti-aromatic carbanions are the least stable.
Updated On: Jan 13, 2026
- \(C>B>D>A\)
- \(A>B>C>D\)
- \(D>A>C>B\)
- \(D>C>B>A\)
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Stability Factor Evaluation
Carbanion stability is influenced by resonance, hybridization, and inductive effects.
Aromatic stabilization enhances carbanion stability.
Step 2: Stability Ranking
Compound (D) exhibits aromaticity, rendering it the most stable.
Compound (A) is anti-aromatic, positioning it as the least stable.
Compounds (B) and (C) demonstrate reduced stability owing to insufficient delocalization.
Consequently, the correct designation is (D).
