No, H2 (hydrogen gas) is not a hydrogen bond; rather, it is a diatomic molecule made up of two hydrogen atoms bonded together by a covalent bond.
A hydrogen bond, on the other hand, is a type of attractive interaction that occurs between a hydrogen atom covalently bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine) and another electronegative atom. The strength of hydrogen bonds is generally weaker than covalent bonds but stronger than van der Waals forces.
In summary, while H2 is a molecular compound formed by covalent bonding, hydrogen bonds occur in different contexts involving interactions between molecules rather than between atoms of the same element.
