Intramolecular Forces

What is the main difference between intermolecular and intramolecular forces?

• Intermolecular forces occur within a molecule, while intramolecular forces occur between molecules.

• Intermolecular forces occur between molecules, while intramolecular forces occur within a molecule.

• Intermolecular forces are stronger than intramolecular forces.

• Intermolecular forces are only found in gases.
