Final answer:

The correct arrangement of intermolecular forces from strongest to weakest is hydrogen bonding > London dispersion forces > dipole-dipole interactions.

Step-by-step explanation:

The correct arrangement of intermolecular forces from strongest to weakest is:

A. hydrogen bonding > London dispersion forces > dipole-dipole interactions

Hydrogen bonding is the strongest intermolecular force and occurs when a hydrogen atom is bonded to a highly electronegative atom like oxygen, nitrogen, or fluorine. London dispersion forces are the weakest intermolecular force and occur between all molecules, whether polar or nonpolar. Dipole-dipole interactions occur between polar molecules and are stronger than London dispersion forces but weaker than hydrogen bonding.
