Study Notes
Intermolecular Forces
- London dispersion forces, also known as van der Waals forces, are responsible for determining the physical and chemical properties of nonpolar molecules.
- London dispersion forces are weak intermolecular forces that arise from temporary dipoles in nonpolar molecules.
- Intermolecular forces refer to the attractive and repulsive forces between molecules, which play a crucial role in determining the physical properties of substances.
- Dipole-dipole forces, a type of intermolecular force, involve the electrostatic forces between two polar molecules.
- The primary function of intermolecular forces is to influence the physical properties of substances, such as boiling point, melting point, and solubility.
