Question
The order of stability of carbanions is
Correct Answer
Option A is the correct answer.
Detailed Explanation
Carbanions are stabilized by electron-withdrawing groups and are destabilized by electron-donating alkyl groups. Therefore, a primary carbanion (with fewer alkyl groups) is more stable than a tertiary carbanion (with more alkyl groups). The order is primary > secondary > tertiary.
Hint
How do alkyl groups affect a negative charge?
