Question

Which of the following alkyl halides is hydrolysed by $S_{N}1$ mechanism?

• A. $C{H}_{3}Cl$
• B. $C{H}_{3}C{H}_{2}Cl$
• C. $C{H}_{3}C{H}_{2}C{H}_{2}Cl$
• D. $(CH{)}_{3}CCl$

Answer 1

The correct option is D $(CH{)}_{3}CCl$

More stable carbocation formed from alkyl halide than reactivity of that alkyl halide will increase to hydrolysis via $S{N}^1$ mechanism.

$3^o$ carbocation $>2^o$ carbocation $>1^o$ carbocation(order of stability.).
