Question

why boiling point order in h2o >hf>nh3 is like this? CAN ANYONE GIVE A STRONG REASON¿

Answer 1

Answer:

These two molecules are expected to have higher boiling (and melting) points. Water molecule has twice as many hydrogen atoms as does HF and, therefore, water can theoretically form more hydrogen bonds than hydrogen fluoride. Thus water is expected to have the highest boiling point of them all, followed by HF.
