The point at which a substance is at complete equilibrium is called? user: a hydrogen bond is a special form of what type of bond

I don't know what the answer to your first question is. All of my teachers have only called it the equilibrium point.  However for your second question, a hydrogen bond is a special type of dipole-dipole attraction.  Only oxygen, nitrogen, and fluorine are able to make them when bonded with hydrogen.  Hydrogen bonding is what makes water have such a high boiling point considering how light the molecule is.

Answer) by studying proton collisions hope this : )
