Intramolecular force. An intramolecular force is any force that holds together the atoms making up a molecule or compound. They contain all types of chemical bonds. They are stronger than intermolecular forces, which are present between atoms or molecules that are not bonded. Types of intramolecular force.
Intermolecular forces are physical forces between molecules. They explain how molecules interact with each other. The strength or weakness of intermolecular forces determine the state of matter of a substance (e.g., solid, liquid, gas) and some of the chemical properties (e.g., melting point, structure).
