Ractivity decreases in the order allylic text halide>2° aliphatic text halide >1° aliphatic text halide.

Q. Arrange the following halides in the decreasing order of $S_{N} 1$ reactivity. $C H_{3} C H_{2} C H_{2} Cl,$ $C H_{2} = C H C H (Cl) C H_{3},$ $(I)$ $(II)$ $C H_{3} c H_{2} C H (Cl) C H_{3}$ $(III)$

$I > II > III$

$II > I > III$

$II > III > I$

$III > II > I$

Ractivity decreases in the order $a ll y l i c ha l i d e > 2^{\circ} a l i p ha t i c ha l i d e$ $> 1^{\circ} a l i p ha t i c ha l i d e .$
