Final answer:
The type of intermolecular forces exhibited by hydrogen bromide molecules, HBr, is all of the above: van der Waals forces, dipole-dipole interactions, and hydrogen bonding.
The correct answer is D.
Step-by-step explanation:
The type of intermolecular forces exhibited by hydrogen bromide molecules, HBr, is d) All of the above. Hydrogen bromide molecules exhibit van der Waals forces, which include dipole-dipole interactions and hydrogen bonding. Van der Waals forces are the collective term for these intermolecular forces, which are responsible for the attractions between molecules.
