The answer is not very. Remember, this is not a “bond” in the traditional sense, it is an electrostatic attraction. The hydrogen bond has only5% or so of the strength of a covalent bond. However, when many hydrogen bonds can form between two molecules (or parts of the same molecule)...

A hydrogen molecule, H2, consists of two hydrogen atoms joined by a covalent bond. Each hydrogen atom needs two electrons to achieve a stable outer electron shell. The pair of electrons is attracted to the positive charge of both atomic nuclei, holding the molecule together. ...
Hydrogenation is a chemical reaction that adds hydrogen to a molecule. Hydrogenation is not thermodynamically favorable at ordinary temperatures, so a catalyst is needed. Usually this catalyst is a metal. Examples of hydrogenated products include margarine, mineral turpentine, and aniline. ...
