(a)
Interpretation:
The given incomplete reaction needs to be completed.
Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electronegative non-metals in the periodic table. The reactivity and electronegativity 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. For example, chlorine can displace bromine from its solution but vice-versa is not possible. The reactivity order for halogens is:
