Van der Waals forces are weak attractions between molecules due to temporary shifts in electron density creating temporary positive and negative charges.
congrats on reading the definition of Van der Waals Forces. now let's actually learn it.
Dipole-Dipole Interaction: A type of intermolecular force that occurs between polar molecules.
London Dispersion Forces: The weakest type of Van der Waals forces, occurring due to temporary shifts in electron density.
Hydrophobic Interactions: Nonpolar interactions that occur when hydrophobic (water-fearing) molecules cluster together in an aqueous solution.
