Question

Which one is least stable carbanions :
​

Answer 1

Explanation:

Greater the no. of alkyl groups on the carbon atom carrying the negative charge, greater would be the inensity of electrons on the negative charge on carbon and hence less stable would be carbanion.

Answer 2

Option a) has the least stable carbanion

Explanation:

A carbanion is an anion that has a formal negative charge and is trivalent (makes three bonds with carbon) (in at least one significant resonance form). A carbanion is a carbon acid's conjugate base in formal terms:

The number of electrons on the negative charge on the carbon atom would increase as the number of alkyl groups increased, making the carbanion less stable as a result.

In option a) there is only one alkyl group.

In option b) there are three alkyl groups (1 $-CH_3$ and 2 alkyls on either side of the negative charge).

In option c) there are two alkyl groups.

Similarly in option d) there are two alkyl groups.

Since the negative charge in option a) has the least number of alkyl groups attached to it, it is the least stable carbanion.
