Intermolecular forces are the forces of attraction or repulsion that occur between molecules. These forces are responsible for many physical properties of substances, such as boiling points, melting points, and solubility. Intermolecular forces are generally weaker than the intramolecular forces (such as covalent or ionic bonds) that hold atoms together within a molecule.
