Match the reactions given in Column-$I$ with their names in Column-$II$:

Column-$I$ (Reactants)	Column-$II$ (Name)
$A$. $R-X + NaI \xrightarrow{\text{dry acetone}} R-I + NaX$	$i$. Electrophilic addition
$B$. $H_3C-Br + AgF \to H_3C-F + AgBr$	$ii$. Finkelstein reaction
$C$. $H_3C-CH_3 + Cl_2 \xrightarrow{hv} H_3C-CH_2Cl + HCl$	$iii$. Swarts reaction
$D$. $CH_2=CH_2 + Br_2 \to BrCH_2-CH_2Br$	$iv$. Free radical substitution

(A-II, B-III, C-IV, D-I) The correct matches are:
$A \to ii$: Finkelstein reaction involves the exchange of halogen with $I^-$ in dry acetone.
$B \to iii$: Swarts reaction involves the synthesis of alkyl fluorides using metallic fluorides like $AgF$.
$C \to iv$: Free radical substitution occurs in alkanes under $UV$ light $(hv)$.
$D \to i$: Electrophilic addition occurs across the double bond of alkenes with halogens.
Therefore,the correct sequence is $A-ii, B-iii, C-iv, D-i$.
