9528527073Hydrogen bondsAttractive 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)0
9528527074Dispersion forces (or London forces)Attractive force occurring between all types of molecules; caused by random electron movement creating instantaneous, temporary dipoles1
9528527075Dipole-dipole forcesAttractive force between + end of one polar molecule and - end of another polar molecule.2
9528527077Dipole-induced dipole forcesAttractive 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 molecule3
9528527079Rank all IMFs from strongest (1) to weakest (6).1. Ion-dipole 2. H-bond 3. Dipole-dipole 4. Ion-induced dipole 5. dipole-induced dipole 6. dispersion4
9528527080Intermolecular forceWEAK attractive force between separate molecules (or particles)5
9528527081Intramolecular ForceSTRONG bond within a molecule6
