Answer: Option (4) is the correct answer.
Explanation:
In solids, there is strong force of attraction between the molecules. Whereas in liquids the force of attraction between the molecules is slightly less as compared to solids.
Thus, we can conclude that [tex]Br_2[/tex] is a liquid at STP and [tex]I_2[/tex] is a solid at STP because molecules of [tex]I_2[/tex] have stronger intermolecular forces than molecules of [tex]Br_2[/tex].
