Arrange the following bromides in the order of reactivity in undergoing $S_{N}1$ reaction:
$(i)$ $(CH_3)_3CBr$
(ii) $CH_3CH_2CH_2Br$
(iii) $(CH_3)_2CHCH_2Br$
(iv) $CH_3Br$

Match the $LIST$-$I$ with $LIST$-$II$:

List-$I$ (Reaction)	List-$II$ (Mechanism)
$A$. Williamson Synthesis	$I$. Electrophilic addition
$B$. Friedel-Crafts Reaction	$II$. Free radical substitution
$C$. Bromination of vinyl benzene	$III$. Nucleophilic substitution
$D$. Chlorination of toluene in light	$IV$. Electrophilic substitution
