Question

In the following halogen compounds, which compound undergoes fastest SN1 reaction? (A) (i) (B) (ii) (C) (iii) (D) None of these

The order of reactivity depends upon the stability of carbocation. Greater the stability of the carbocation faster will be the rate of reaction. Hence, the order of reactivity will be 3° alkyl halide > 2° alkyl halide > 1° alkyl halide > methyl halide.

Q. In the following halogen compounds, which compound undergoes fastest $S_{N} 1$ reaction?

(i)

(ii)

(iii)

None of these

The order of reactivity depends upon the stability of carbocation. Greater the stability of the carbocation faster will be the rate of reaction. Hence, the order of reactivity will be $3^{\circ}$ alkyl halide $>$ $2^{\circ}$ alkyl halide $>$ $1^{\circ}$ alkyl halide $>$ methyl halide.
