Correct order of stability of carbanion is
- c > b > d > a
- a > b > c > d
- d > a > c > b
- d > c > b > a
The Correct Option is D
Solution and Explanation
Among the given compounds, compound (d) is aromatic, which greatly enhances its stability due to resonance stabilization. Compound (a) is antiaromatic, making it the least stable among the given options.
Compound(b) and compound (c) have sp3 hybridized carbon atoms bearing the negative charge. Based on angle strain theory, compound (c) is more stable than compound (b) due to its ring structure.
