are electrostatic forces that occur when oppositely charged ions attract each other.
Ion-ion interactions
an attractive force between a charged ion and a neutral molecule with a dipole.
ion-dipole interaction
an electrostatic force that occurs between two polar molecules with permanent dipoles
dipole-dipole interaction
an electrostatic attraction between a hydrogen atom and an electronegative atom.
hydrogen bond interaction
a type of weak intermolecular force, considered a subset of Van der Waals forces, that occurs between all molecules due to temporary fluctuations in electron distribution, creating temporary dipoles which then induce dipoles in neighboring molecules
London dispersion interaction
