The present paper carries the analysis of various contributions into the total energy of intermolecular interaction (IMI) DELTAU(S) in infinitely diluted solutions, that are formed by aliphatic (including alcohols) and aromatic polar compounds with polar and non-polar, associated and non-associated solvents at 298 K. The calculation within the frames of the earlier suggested continuum method of IMI energy and of its separate constituents in the systems studied is carried out, and the cases of their deviations from experimentally determined analogues are analyzed to resolve the above task. Compounds are distinguished for which there is a strengthening or weakening of the energy of the hydrogen bond between the molecules of solute and solvent in solution, if compared with the analogous value between the individual liquid molecules. Quantitative values of the energetic expenditure for the destruction of associative bonds in solvents upon formation of solutions are estimated.
