Does Ammonia Exhibit Hydrogen Bonding
The chemical formula for ammonia is\ (NH_ {3}\). Looking at its molecular structure, the nitrogen atom is quite electronegative, and there are lone pairs of electrons on the nitrogen atom, and the hydrogen atom is connected to the nitrogen atom.
The formation of a hydrogen bond requires two conditions: first, a hydrogen atom connected to an atom with a large electronegativity; second, an atom with a large electronegativity and a lone pair of electrons. In an ammonia molecule, hydrogen is connected to a nitrogen with a large electronegativity, and the nitrogen atom has a lone pair of electrons, both of which are available.
So ammonia can form a hydrogen bond. When ammonia molecules are polymerized, the lone pair electrons of the nitrogen atom in one ammonia molecule and the hydrogen atom in the other ammonia molecule attract each other, and this attraction is the force of the hydrogen bond. The existence of this hydrogen bond has a great impact on the physical properties of ammonia. If the boiling point of ammonia is relatively high, if it is only based on van der Waals force theory, its boiling point should be very low. However, due to the hydrogen bond, the force between the ammonia molecules is increased, resulting in an increase in its boiling point. And ammonia has great solubility in water, which is also related to hydrogen bonds. Ammonia molecules and water molecules can form hydrogen bonds, which enhances the interaction between the two, so ammonia is easily soluble in water.
In summary, ammonia does have hydrogen bonds, which is based on its molecular structure and hydrogen bond formation conditions.
