The proton donor-acceptor complexes formed by 2-haloethanols with tetrahydrofuran in carbontetrachloride solution have been studied. The area of the OH-stretching band corresponding to the intermolecularly H-bonded complexes was plotted against concentration of the THF. From the shape of the curves the relative strength of the intramolecular H-bonds in 2-haloethanols appears to vary in the order F > Br > Cl > I. The anamoly in the relative strength of chloro and bromoethanol was checked from the results of complexes formed by 2-Cl and 2-Brethanol with triethylamine under similar conditions. The order obtained is in agreement to that in the case of THF.
