Question

The boiling point of CH4 is much lower as compared to that of NH3, H20, HF . Explain why?

Answer 1

NH3,H20,HG all this are ionically bonded so, they have a strong electrostatic force between them so they are tightly bonded but CH4 is an organic compound which is bonded by sharing electrons that is they are covalent bonds so they don't have any electrostatic force between them so here the atoms are no so strongly bonded so when we heat them they break down easily so, we say it has low boiling point

Answer 2

NH 3,H20 and HF can form hydrogen bonding with water but ch4 can't do this.for breaking this hydrogen bonding energy is so high.for this The boiling point of CH4 is much lower as compared to that of NH3, H20, HF.
