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. $(C{H}_3{)}_{3}CCl$

Answer 1

Answer: (D)

More stable carbocation formed from alkyl halide than reactivity of that alkyl halide will increase to hydrolysis via $S{N}^1$ mechanism.
$3^{\circ }$ carbocation $>2^{\circ }$ carbocation $>1^{\circ }$ carbocation(order of stability.).
