Vedclass · Answer

(B) The stability of carbanions is determined by the inductive effect ($+I$ effect) and resonance.$(1) (CH_3)_3C^-$ is a tertiary carbanion,$(2) (CH_3)_2CH^-$ is a secondary carbanion,and $(3) CH_3CH_2^-$ is a primary carbanion. The $+I$ effect of alkyl groups destabilizes the carbanion,so stability follows the order: $1^circ > 2^circ > 3^circ$.$(4) C_6H_5CH_2^-$ is a benzyl carbanion,which is stabilized by resonance with the phenyl ring,making it more stable than the alkyl carbanions.Thus,the decreasing order of stability is: $C_6H_5CH_2^- (4) > CH_3CH_2^- (3) > (CH_3)_2CH^- (2) > (CH_3)_3C^- (1)$.

Which of the following is the correct decreasing order of stability of carbanions?
$(1) (CH_3)_3C^-$
$(2) (CH_3)_2CH^-$
$(3) CH_3CH_2^-$
$(4) C_6H_5CH_2^-$
