Q.
The stability of carbanions in the following
AIPMTAIPMT 2008Organic Chemistry – Some Basic Principles and Techniques
Solution:
The carbanion with more s-character is more stable. Thus, the order of stability is
$R C \equiv \overset{\ominus}{ C }> C _{6} H _{5}^{\ominus}>R_{2} C =\overset{\ominus}{ C H}>R_{3} C -\overset{\ominus}{ C }_{2}$
