Here's why:

* Hydrogen bonds are special intermolecular forces that occur between a hydrogen atom covalently bonded to a highly electronegative atom (like oxygen, nitrogen, or fluorine) and an electron pair in the lone pair of an adjacent electronegative atom.

* H₂ only has a single covalent bond between the two hydrogen atoms. There are no lone pairs or highly electronegative atoms involved.

* The interaction between H₂ molecules is primarily due to van der Waals forces, which are much weaker than hydrogen bonds.
