Vedclass · Answer

(C) The stability of carbanions is primarily governed by the inductive effect ($+I$ effect) and resonance.$1$. Compound $IV$ is the most stable because the negative charge on the carbon is delocalized into the phenyl ring through resonance.$2$. Among the remaining alkyl carbanions $(I, II, III)$,stability decreases as the number of alkyl groups attached to the anionic carbon increases. This is because alkyl groups exert a $+I$ effect,which increases the electron density on the anionic carbon,thereby destabilizing it.$3$. Thus,the stability order is $1^{\circ} > 2^{\circ} > 3^{\circ}$.$4$. Comparing the given structures:- $I$ is a $1^{\circ}$ carbanion.- $II$ is a $2^{\circ}$ carbanion.- $III$ is a $3^{\circ}$ carbanion.- $IV$ is resonance-stabilized.Therefore,the increasing order of stability is $III < II < I < IV$.

Column-$I$	Column-$II$
$A$. $CH_3-O^{+}=CH-CH_3$	$1$. Stable due to resonance
$B$. $F_3C^{+}$	$2$. Destabilised due to inductive effect
$C$. $(CH_3)_3C^{-}$	$3$. Stabilised by hyperconjugation
$D$. $CH_3-CH^{+}-CH_3$	$4$. $A$ secondary carbocation

List-$I$ (Carbocation)	List-$II$ (Type)
$A$. $CH_3-C^{+}(CH_3)-CH_3$	$I$. Secondary carbocation
$B$. $CH_3-C^{+}H-CH_3$	$II$. Methyl carbocation
$C$. $CH_3-CH_2^+$	$III$. Primary carbocation
$D$. $CH_3^+$	$IV$. Tertiary carbocation

The stability of carbanions follows the order:
$I: CH_3CH_2CH_2\bar{C}H_2$
$II: CH_3\bar{C}HCH_2CH_3$
$III: (CH_3)_3\bar{C}$
$IV: CH_3\bar{C}(Ph)CH_2CH_3$
