Vedclass · Answer

(C) The stability of a carbanion is directly proportional to the percentage of $s$-character in the hybrid orbital of the carbon atom bearing the negative charge. $1$. In $CH\equiv C^{-}$,the carbon is $sp$ hybridized ($50\% \ s$-character). $2$. In $CH_2=CH^{-}$,the carbon is $sp^2$ hybridized ($33.3\% \ s$-character). $3$. In $CH_3-CH_2^{-}$,the carbon is $sp^3$ hybridized ($25\% \ s$-character). Higher $s$-character means the electrons are held closer to the nucleus,increasing stability. Therefore,the correct order of stability is: $CH\equiv C^{-} > CH_2=CH^{-} > CH_3-CH_2^{-}$.

The correct order of stability for the following carbanions is:
$CH_2=CH^{-}, CH_3-CH_2^{-}, CH\equiv C^{-}$
