- Intramolecular forces act within a molecule and hold it together through covalent or ionic bonds.
- Intermolecular forces are attractive or repulsive forces that act between molecules in a substance.
- Types of intermolecular forces include hydrogen bonds, Van der Waals forces, and London dispersion forces.
- Hydrogen bonds, for example, create strong attractions between molecules, impacting properties like melting and boiling points.
- Van der Waals forces, including London dispersion forces, result from temporary attractive forces between molecules, especially nonpolar substances.
