CONDITIONS FOR FORMING STRUCTURES WITH STRONG HYDROGEN BONDS

Based on an analysis of literature data, it is concluded that protonation of organic molecules B in B-AH fluid binary systems is accompanied by the formation of (B center dot center dot center dot H center dot center dot center dot B)(+) and (A center dot center dot center dot H center dot center dot center dot A)(-) ions with strong hydrogen bond in which the proton is delocalized between molecules B or ions A(-). Conditions for forming neutral structures (A(-)H(+)center dot center dot center dot B) with strong hydrogen bonds are analyzed. It is demonstrated that the most important condition for forming these structures is their solvation in fluid solutions.
