On the hydrogen bond of ammonia
Between heaven and earth, everything has its own reason, and the wonders of creation exist in the microscopic. Ammonia ($NH_3 $) has a unique molecular structure and contains the mystery of hydrogen bonds.
Ammonia molecules are composed of one nitrogen atom and three hydrogen atoms. The nitrogen atom, which likes electrons and has strong electronegativity, is connected to the hydrogen atom, so that the electron cloud outside the hydrogen atom is biased towards the nitrogen atom. At this time, the hydrogen atom is like a naked nucleus, showing positive electricity. In adjacent ammonia molecules, the lone pair of electrons of the nitrogen atom is negatively charged, and the hydrogen atom with positive electricity in other ammonia molecules attracts each other. This attractive force, that is, the hydrogen bond is also.
The hydrogen bond has a profound impact on ammonia. Looking at its physical properties, the boiling point of ammonia is different from common sense. In terms of its relative molecular mass, the boiling point should be quite low, but due to the action of hydrogen bonds, the intermolecular force is greatly increased, resulting in an increase in the boiling point. At room temperature, ammonia is gaseous and easy to liquefy. And ammonia has a very large solubility in water, and because hydrogen bonds can be formed between ammonia molecules and water molecules, the two attract each other, making ammonia highly soluble in water.
Furthermore, the chemical properties of ammonia are also influenced by hydrogen bonds. In some reactions, hydrogen bonds can affect the activity and reaction path of ammonia molecules. Due to its existence, ammonia molecules can build a specific spatial structure, which in turn affects the rate and direction of chemical reactions.
Although the hydrogen bond of ammonia is inconspicuous, it plays a key role in the various properties of ammonia. Exploring this microscopic mystery, the wonder of creation, the wonder of material change, really lies in the exquisite microstructure.
