Remember: Any halogen placed above in periodic table will oxidize halide ion of halogen placed below. Cl2 + 2 Br- arrow Br2 + 2Cl- Tendancy to undergo oxidation of halide ion increases down the group.

Q. $B r^{-}$ is converted into $B r_{2}$ by using :

$C l_{2}$

conc. $H Cl$

$H B r$

$H_{2} S$

Remember : Any halogen placed above in periodic table will oxidize halide ion of halogen placed below.
$C l_{2} + 2 B r^{-} \to B r_{2} + 2 C l^{-}$
Tendancy to undergo oxidation of halide ion increases down the group.
