CONDITIONS FOR THE FORMATION OF IONS WITH STRONG QUASI-SYMMETRIC HYDROGEN-BONDS

The conditions necessary for the formation of ions with strong hydrogen bonding (B...H...OH2)+ are determined: 1) acid-base interaction achieves the stage of ion formation; 2) the base molecules contain atoms with unshared electron pairs; and, 3) the heat of protonization of a base molecule in the gas phase is not less than the heat of protonization of a water molecule (711 kJ/mole), but not more than the value determined by the difference between the energy of breaking the strong hydrogen bond in H5O2+ and the heat of the hydrogen bond in a dimer of water, i.e., -836 kJ/mole. © 1990 Plenum Publishing Corporation.
