Final answer:
Hydrogen bonding is the strongest IMF in H2, significantly stronger than dipole-dipole interactions or London dispersion forces.
Explanation:
Hydrogen bonding is the strongest IMF in H2. It is a type of intermolecular force that occurs when a hydrogen atom is bonded to a highly electronegative atom like oxygen, nitrogen, or fluorine. This creates a strong attraction between molecules, significantly stronger than dipole-dipole interactions or London dispersion forces.
