Question

Why does water has a higher boiling point than hydrogen fluoride?

Answer 1

because hydrogen can form a greater number of hydrogen bonds due to having an equal number of hydrogen bond donor and accepter .each hydrogen atoms can be Hydrogen bond accepter each of the lone pair in oxygen can be donor .but in HF there is one hydrogen accepter and theoretically three hydrogen donor. This imbalanced ratio inevitably leaves some acceptors without a donor. Imagine this as two dance parties; one party has two men and two women but the other has one man and three women. Obviously fewer bonds can be successfully formed in the latter, assuming that everything is monogam.
