Why does hydrogen is taken specially in intermolecular forces?

[abi.ayan]

Though there are other atoms with less electronegativity which can form effective attraction forces,why hydrogen is taken as a speacial case?

 

[Simon Bridge]

Simplest atom.

Are you asking why you see things called "hydrogen bonds" but not "other bonds"? It's nothing particular to hydrogen per se, it's just that there's so much of it out there and it's so often bound to oxygen and nitrogen (for example) in organic chemistry and it's able to form those weaker type bonds in solution. It's a "ubiquity" thing, not a "special" thing.
