Vedclass · Answer

(B) $1$. The stability of carbanions is primarily governed by resonance and the inductive effect. $2$. Resonance: $Q$ $(C_6H_5\bar{C}H_2)$ is stabilized by resonance with the benzene ring,and $S$ $(H_2\bar{C}^{-}CH=CH_2)$ is stabilized by resonance with the double bond. $Q$ is more stable than $S$ due to the greater delocalization of the negative charge over the aromatic ring. $3$. Inductive Effect: Alkyl groups exhibit a $+I$ effect,which destabilizes carbanions. $P$ $(\bar{C}H_3)$ has no alkyl groups,while $R$ $((CH_3)_2\bar{C}H)$ has two electron-donating methyl groups. Thus,$P$ is more stable than $R$. $4$. Combining these factors,the stability order is $R < P < S < Q$.

What is the increasing order of stability for the carbanions $P: \bar{C}H_3$,$Q: C_6H_5\bar{C}H_2$,$R: (CH_3)_2\bar{C}H$,and $S: H_2\bar{C}^{-}CH=CH_2$?
