The high boiling point of hydrogen fluoride can be explained in terms of?
covalent bonds.
dative bonds.
dipole-dipole bonds
electrovalent (ionic) bonds.
hydrogen bonds.

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.
