Surface Tension

• Permanent dipoles-permanent dipoles (London dispersion) interactions occur when two polar molecules interact with one another due to their partial positive and negative charges.
• Intermolecular forces can be classified as either permanent dipoles-permanent dipoles (London dispersion) interactions or induced dipoles-induced dipoles (Keesom) interactions
• The intermolecular forces between molecules are the attractive or repulsive forces that exist between atoms, ions, or molecules.
