Dipole moments and molecular complexes
Bedford College, London, G.-B..
Evidence is given that hydrogen bonding between weak acids and weak bases involves only a relatively small contribution to the dipole moment of the complex formed. As the strength of the acid or base or both is increased the apparent contribution of ion pair forms becomes more important. It is suggested, however, that in the association of acids of medium strength with tri-n-butylamine or triethylamine the energies of the hydrogen bonded and ion pair forms become nearly equal, with the result that the two exist in tautomeric equilibrium in solution.
