Water and the ammonium ion have the same tetrahedral electronic geometry and molecular mass, 18 g/mol. use intermolecular forces and physical properties to explain why water has a higher boiling point than the ammonium ion.

Hydrogen bond is the inter molecular force that hold the molecules of the water together while the molecule of ammonium ion are held together by dipole dipole interaction. The hydrogen bond is stronger than the dipole dipole interaction, thus it requires an higher amount of heat energy to break the hydrogen bond which hold the molecules of the water together, that is why water has an higher boiling point than ammonium ion even though they have the same molecular mass and electronic shape.
