The product of which of the following reactions undergo hydrolysis by S _ N 1 mechanism?

Step-by-step solution

So only (B) and (C) formed stable benzylic carbocation so it will undergo hydrolysis by S _ N 1 mechanism. S _ N 1 reactivity order : benzylic 3^ 2^ 1^ S _ N 2 reactivity order : 1^ 2^ 3^
