Question

why does NH3 has higher melting point than HF?​

Answer 1

Answer:

Explanation:

As fluorine is more electronegative than nitrogen, the H-F bonds are much more polar than the N-H bonds. Due to the higher partial charges on H and F in HF, a hydrogen bond between HF molecules is stronger than that between NH3 molecules. The higher boiling point of HF is thus due to stronger H-bonds

Answer 2

Explanation:

I think that has to do with bonds there are three bonds in NH3 whereas there is only one bond in HF
