Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electro-negative non-metals. The reactivity and electro-negativity of elements decreases down in the group therefore, fluorine is most reactive halogen and iodine is least reactive halogen. In other words, in displacement reactions, a more reactive halogen can displace a less reactive halogen to form product such as chlorine can displace bromine from its solution but vice-versa is not possible. The reactivity order for halogens is
(b)
Interpretation:
The given chemical reaction needs to be balanced.
