Attractive force between an ion and the oppositely charged end of a polar molecule.
Back
Dipole-dipole forces
Front
Attractive force between + end of one polar molecule and - end of another polar molecule.
Back
Dipole-induced dipole forces
Front
Attractive force occurring between polar molecules and nonpolar molecules; the nonpolar molecule's electron cloud is temporarily distorted (polarized) due to the presence of the + or - end of the polar molecule
Back
Intermolecular force
Front
WEAK attractive force between separate molecules (or particles)
Back
Dispersion forces (or London forces)
Front
Attractive force occurring between all types of molecules; caused by random electron movement creating instantaneous, temporary dipoles
Back
Ion-dipole
Front
Attractive force between an ion and the oppositely charged end of a polar molecule
Back
Hydrogen bonds
Front
Attractive force between an H atom (covalently bonded to an electronegative atom - O, N, F) and lone pair electrons (on another electronegative atom - O, N, F)
