The high boiling point of hydrogen fluoride can be explained in terms of?

A.

covalent bonds.

B.

dative bonds.

C.

dipole-dipole bonds

D.

electrovalent (ionic) bonds.

E.

hydrogen bonds.

Correct answer is E

Hydrogen fluoride is formed through covalent bonding (electron sharing) between a hydrogen atom and a fluorine atom. 

The reason is the strong electronegativity of the fluorine atom, which causes hydrogen and fluorine atoms to form hydrogen bonds in the liquid phase.
