Correct answer is (b) 1 - (ii), 2- (i), 3 - (iv), 4 - (v)

List I (Reagent)		List II (Electrophiles)
1	$C l_{2} + A lC l_{3}$	i	$N O_{2}$
2	$H N O_{3} + H_{2} S O_{4}$	ii	$Cl \dots . Cl \dots . A lC l_{3}$ or $C l^{+}$
3	$H_{2} S_{2} O_{7}$	iii	$S O_{3} H$ (or $H_{2} S O_{4} + S O_{3})$
4	$B r_{2} + F e$	iv	$S O_{3}$
		v	$B r \dots B r \dots F e B r_{3}$ or $B r^{+}$
