It is because of small size and high electronegativity

Meghna Thapar 5 years, 10 months ago

Hydrogen bonding is a very special intermolecular force that occurs in polar molecules when a hydrogen atom is bonded to a highly electronegative atom. Thus the effect of hydrogen bonds can be very large. They are so strong that they seem like weak covalent bonds. Thus, the name hydrogen bond. Hydrogen forms only one hydrogen bond with flourine in HF because flourine is more electronegative and its electrons are more stabilized and not ready to be donated to some accepter. Each of the hydrogen atoms can be hydrogen bond acceptors; each of the lone pairs on the oxygen can be donors.
