Question

What is the specific feature of , , and that causes them to play a role in hydrogen bonding?

, , and are all three 

 atoms with 

 electronegativity. When hydrogen is bonded to one of these atoms an especially 

 dipole is created.

Answer 1

Hydrogen bonds can exist between atoms in different molecules or in parts of the same molecule.Mainly through electrostatic attraction, the donor atom effectively shares its hydrogen with the acceptor atom, forming a bond.
