Answer:
b. ICl experiences dipole-dipole interactions
Explanation:
The molecule with the stronger intermolecular forces will have the higher boiling point.
In Br₂, the Br-Br bond has a dipole moment of zero, because the two atoms are identical.
In ICl, the I-Cl bond, has two different atoms. One must be more electronegative than the other, so there will be a non-zero bond dipole.
ICl will have the higher boiling point.
a is wrong. Br₂ is nonpolar, so it has no dipole-dipole interactions.
c is wrong. Br₂ cannot form hydrogen bonds, because there is no hydrogen.
d is wrong. ICl has dipole-dipole interactions.
