Question

Why do HF and H2O have abnormal high boiling point

Answer 1

Answer:

each HF molecule has only one hydrogen atom. And hence, water molecule takes part in extensive and more hydrogen bonding than Hydrofluoric acid. Water molecule through its extensive hydrogen bonding forms a bulky molecule and it is very difficult to break its bonds. ... Thus H2O has a higher boiling point than HF.
