Vedclass · Answer

(D) The rate of $S_N 1$ reaction depends on the stability of the carbocation intermediate formed during the rate-determining step.$S_N 1$ reactivity order is: $3^{\circ} > 2^{\circ} > 1^{\circ} > CH_3-X$.$A$: $2-$bromo-$3-$methylbutane is a $2^{\circ}$ halide.$B$: $2-$chloro-$3-$methylbutane is a $2^{\circ}$ halide.$C$: Chloromethane is a $1^{\circ}$ halide.$D$: $2-$bromo-$2-$methylpropane is a $3^{\circ}$ halide.Since $3^{\circ}$ carbocations are the most stable,$2-$bromo-$2-$methylpropane will undergo $S_N 1$ reaction the fastest.
