Vedclass · Answer

(C) The reactivity of compounds towards $S_N1$ substitution depends on the stability of the carbocation intermediate formed after the departure of the leaving group $(Cl^-)$.$1$. The carbocations formed are:$(a)$ $(CH_3)_2CH-CH_2^+$ (primary carbocation with branching)$(b)$ $CH_3CH_2^+$ (primary carbocation)$(c)$ $CH_3O-C_6H_4-CH_2^+$ (benzylic carbocation stabilized by $+M$ effect of $-OCH_3$ group)$(d)$ $C_6H_5-CH_2^+$ (benzylic carbocation stabilized by resonance)$2$. Stability order of carbocations:$CH_3O-C_6H_4-CH_2^+ > C_6H_5-CH_2^+ > (CH_3)_2CH-CH_2^+ > CH_3CH_2^+$$3$. Since reactivity $\propto$ stability of carbocation,the increasing order of reactivity is:$(b) < (a) < (d) < (c)$

Increasing order of reactivity of the following compounds for $S_N1$ substitution is:
$(a)$ $(CH_3)_2CH-CH_2Cl$
$(b)$ $CH_3CH_2Cl$
$(c)$ $CH_3O-C_6H_4-CH_2Cl$
$(d)$ $C_6H_5-CH_2Cl$
