The hydrofluoric acid has greater boiling point than water, ammonia or methane molecules.

<h3>What is boiling point? </h3>

The temperature at which the pressure of the surroundings upon a liquid is equal to the pressure which is exerted by the vapour of the liquid.

<h3>What is Hydrogen bond? </h3>

The intermolecular attraction between most electronegative atom and the hydrogen atom is termed as hydrogen bond.

Since greater the electronegativity of atom greater will be the strength of hydrogen bond.

As, F atom has greater electronegativity than O-atom which has further greater electronegativity than N atom and than Carbon atom.

So the strength of hydrogen bond is as follows:

hydrofluoric acid > water molecule > ammonia molecule > methane molecule.

Thus, we concluded that hydrofluoric acid has greater boiling point than water, ammonia or methane molecules.
