The order of reactivity of halides towards S N 1 reaction is benzyl > allyl >3°>2°>1°> Me Therefore, the orrde of hydrolysis by S N 1 mechanism is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/380279f7f7d2b8251db3fe437a28f631-.png" />

Q. Which one of the following is more readily hydrolysed by $S_{N} 1$ mechanism?

$(C_{6} H_{5})_{2} C (C H_{3}) B r$

$C_{6} H_{5} C H_{2} B r$

$C_{6} H_{5} C H (C H_{3}) B r$

$(C_{6} H_{5})_{2} C H B r$

The order of reactivity of halides towards $S_{N} 1$ reaction is

benzyl $>$ allyl $> 3^{\circ} > 2^{\circ} > 1^{\circ} >$ Me

Therefore, the orrde of hydrolysis by $S_{N} 1$ mechanism is
