The comparatively high b.pt. of HF is due to

Options

A. high reactivity of fluorine
B. small size of hydrogen atom
C. formation of hydrogen bonds and consequent association
D. high IE of fluorine

Answer

C

Explanation

Intramolecular hydrogen bonding is found in `(HF)_(n)` due to higher electronegativity of fluorine atoms.
`underset("hydrogen bonding")(......H-F......H-F....H-F.....)`
Hydrogen bonding is helpful in the association of HF molecule, so HF is found in liquid form.
