Question

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

• A. ion - ion interaction
• B. ion - dipole interaction
• C. london force
• D. hydrogen bond

Answer 1

The correct option is D hydrogen bond

Dipole-dipole interaction depends on the inverse cube of distance between the molecules. Hydrogen bonding is an example of dipole-dipole interaction. The strength of the interaction depends on the magnitude of dipole moment of polar molecule, size of the molecule and charge and size of the ion.
