Inorganic Chemistry , 16 10 , Levanov , U. Hydrogen bonding also accounts for the higher boiling point of HF compared to other hydrogen halides. Another common question about the chemistry of hydrofluoric acid is whether the HF molecule is polar.

The chemical bond between hydrogen and fluorine is a polar covalent bond in which the covalent electrons are closer to the more electronegative fluorine.

That makes it easier to generally understand the difference between strong and weak acids. Also, I didn't know that very concentrated solutions of HF can actually behave like a strong acid. I'll definitely keep that in mind. Thank you all for your answers, they were very helpful! Jump to. The behavior of hydrofluoric acid greatly depends on its concentration in water. The chemical bond in this species is strong enough to limit acidity, so hydrofluoric acid is a very weak acid in dilute solution.

Concentrated HF solutions behave much like a strong acid. Hydrogen bonding also causes HF to have a higher boiling point than the other hydrogen halides.
