For 10 points, name this type of extremely strong dipole-dipole interaction "accepted" by nitrogen and oxygen and "donated" by its namesake, the lightest element.
This phenomenon confers stability to the enol tautomer of beta-keto ketones as well as to dimerized carboxylic acids, while the strongest, symmetric form, occuring at around forty kilocalories per mole, is illustrated by the bifluoride ion. Different numbers of this phenomenon account for why the human genome contains about as many C bases as G bases. Responsible for (*) protein secondary structure like beta sheets, it lowers the volatility of and raises the heat of vaporization of water.
