Q. Consider the following carbanions

$1.$ $CH_{3}-\overset{\ominus}{C}H_{2}$ $2.$ $CH_{2}=\overset{\ominus}{C}H$ $3.$ $CH\equiv \overset{\ominus}{C}$

Correct the order of stability of these carbanions in decreasing order is

Solution:

Stability of carbanion (when hybridisation of $\overset{\ominus}{C}$ is different) is directly proportional to S character.

Stability $ \propto $ s%
