The intermolecular interaction that is dependent on the inverse cube of distance between the molecules is:

1. Ion - ion interaction
2. Ion - dipole interaction
3. London force
4. Hydrogen bond

Correct answer: Ion - dipole interaction

Solution

Ion-dipole interactions arise from the electrostatic attraction between an ion and a polar molecule, and their strength decreases with the cube of the distance between them, making this relationship distinct from other types of intermolecular forces.
