ANSWER:
In general, of all the existing bonds, the molecule which has hydrogen bonding tends to show better or unusual physical and chemical properties because these hydrogen bonding interactions are the strongest of all the forces.
In ammonia (NH3), hydrogen bonding exists between the more electronegative nitrogen (N) and hydrogen (H) atoms, hence ammonia shows an unusually high melting point.
