Does NH3 Form Hydrogen Bonds
Does ammonia ($NH_3 $) form a hydrogen bond?
In ammonia molecules, the nitrogen atom has a high electronegativity, and there are lone pairs of electrons on the nitrogen atom, and the hydrogen atom is connected to the nitrogen atom. Because the hydrogen atom is bonded to the highly electronegative nitrogen atom, its electron cloud is biased towards the nitrogen atom, so that the hydrogen atom has a partial positive charge. When such a hydrogen atom is close to the lone pair of electrons of the nitrogen atom in another ammonia molecule, a strong interaction will occur, which is a hydrogen bond. Therefore, ammonia can form hydrogen bonds. It can also be proved from its physical properties, such as the relatively high boiling point of ammonia and its great solubility in water, all due to the existence of hydrogen bonds between molecules.
