Ammonia Hydrogen Bonding
Hydrogen Bonding Theory of Ammonia
Ammonia is also a normal substance of transformation. Whether it exists in hydrogen bonds is of considerable value.
The formation of hydrogen bonds must have two important factors. First, hydrogen is connected to atoms with strong electronegativity, such as nitrogen, oxygen, and fluorine; second, the hydrogen is nearby, when there are atoms rich in solitary pairs of electrons and strong electronegativity.
Ammonia molecules, the chemical formula is $NH_ {3} $. Nitrogen, which has strong electronegativity, is connected to hydrogen. Nitrogen atoms have solitary pairs of electrons, and their electronegativity is greater than that of hydrogen. It is between ammonia molecules that can form hydrogen bonds. Hydrogen is connected to nitrogen, hydrogen is positive, and the solitary pair electron of nitrogen in the ortho-ammonia molecule is attracted to the hydrogen, which is the formation of hydrogen bonds.
The existence of hydrogen bonds has a great impact on the properties of ammonia. For example, the boiling point of ammonia is higher than that of homologous phosphine and hydrogen arsenide, which is caused by hydrogen bonds. The force of hydrogen bonds enhances the interaction between molecules, and more energy is required to break the attractive force between molecules when causing boiling.
In addition, the solubility of ammonia in water is also related to hydrogen bonds. Ammonia molecules and water molecules can form hydrogen bonds, resulting in high solubility of ammonia in water.
From this perspective, ammonia does have hydrogen bonds, which play a key role in its physical and chemical properties, and cannot be ignored in the research and use of chemistry.
