Solution

The correct option is C Assertion is correct but Reason is incorrect
Benzyl bromide when kept in acetone and $H_{2} O$ produces benzyl alcohol

$P h C H_{2} B r w a t e r - --- \to a c e t o n e P h C H_{2} - O H$

The reaction follows $S_{N} 1$ mechanism. ( Since $P h - C H_{2}^{+}$ carbocation intermediate is more stable)

Thus, benzyl halides undergo hydrolysis by $S_{N} 1$ mechanism and not $S_{N} 2$ .

Hence, Assertion is correct but Reason is incorrect.
