Question

Secondary butyl chloride undergo alkaline hydrolysis in the polar solvent by ___________ mechanism.

• A. $S_{N}2$
• B. $S_{N}1$
• C. $S_{N}1$ and $S_{N}2$
• D. $E2$

Answer 1

Answer: (B)

$S_{N}1$

In polar medium sec. alkyl halide undergo $S_{N}1$ mechanism.

The carbocation intermediate formed during the $S_{N}1$ mechanism is very stable in polar solvents.

So, option B is correct.
