Solution:
- Halogens are all good oxidising agent and their oxidising power decreases from top to bottom $\left(F _2\right.$ to $\left.I _2\right)$ in group. Any halogen above in group oxidises halides down in group from their aqueous solution. Hence, $Cl _2$ can oxidise $Br^{-}$to $Br _2$, $I^{-}$to $I _2$ but cannot oxidise $F^{-}$to $F _2$ rather $F _2$ can oxidise $Cl^{-}$to $Cl _2$.
