Question

What is the correct order of stability for carbanions?
Options
A Tertiary > Secondary > Primary > Methyl
B Methyl > Primary > Secondary > Tertiary
Correct Answer
C All are equally stable
D Methyl > Tertiary > Secondary > Primary
Correct Answer

Option B is the correct answer.

Detailed Explanation

Carbanion stability is opposite to carbocations: methyl is most stable, and tertiary is least stable because alkyl groups are electron-donating and destabilize the negative charge.

Hint

Least substituted carbanion is most stable.
