Unformatted text preview: + end of an adjacent highly polar molecule, but hydrogen-bonding IMFs are much stronger attractive forces. London dispersion IMFs London dispersion forces are found to some degree in all covalent substances, however, they are the only attractive forces that hold together groups of non-polar covalent molecules. At any given instant in time, non-polar molecules can become slightly polar due to the random motion of their electrons into non-symmetrical arrangements, and thus they can acquire an “instantaneous dipole moment”. This gives rise to the weak attractions that exist between non-polar molecules....
