Question:- What type of intermolecular forces are present in NH3?

Answer: The characteristic intermolecular forces found in NH3 or ammonia are hydrogen bonds.

The type of intermolecular force that is present within ammonia molecules is hydrogen bonding, which is considered to be relatively strong. This is due to the high electronegativity of nitrogen in NH3 molecule; when forms a bond with hydrogen, this results in a high partial negative charge on nitrogen atoms and a high partial positive charge on hydrogen atoms. Therefore, one of the partially positive hydrogen atoms of one ammonia molecule is pulled towards another molecule, towards the partially negative nitrogen, thus forming a hydrogen bond. Although these hydrogen bonds are not as strong as the ones found in water, they are stronger than such intermolecular forces as dipole-dipole interactions, or Van der Wals forces. The existence of hydrogen bonding in ammonia leads to a relatively higher boiling point for a molecule of its size; it also affects its physical characteristics and chemical reactions.
