Question

Is it true that the physical existence of the hydrogen bond is proven? if so then what actually is it about?

Answer 1

I'm not satisfied with the rationale for the intermolecular attraction known as hydrogen bonding. In my book, it states that

Hydrogen bonding is a special type of intermolecular attraction between the hydrogen atom in a polar bond (particularly H ¬ F, H ¬ O, and H ¬ N) and non-bonding electron pair on a nearby small electronegative ion or atom usually F, O, or N (in another molecule).
