The reason iodine, I2, exists as a solid at room temperature, while bromine, Br2, exists as a liquid at the same temperature, is because:

Iodine exhibits hydrogen bonding, while bromine exhibits only London dispersion forces.

Iodine molecules create stronger London dispersion forces than do bromine molecules.

Bromine exists only as a gas at all temperatures.

Bromine forms fewer dipole-dipole interactions than does iodine.
