intermolecular forces

forces between molecules

molecules

fill in the blank

intermolecular forces do not bond atoms to form compounds (a chemical change); instead, they bind _______ together without changing the compound (a physical change)

dipole-dipole forces

forces between neighboring polar molecules caused by the attraction of oppositely charged ends

polar

fill in the blank

the more ______ the molecule, the greater the dipole-dipole force and the higher the boiling point

london forces

weak intermolecular forces resulting from momentary dipoles in molecules

london forces
