Ch4 Hydrogen Bonding
Between methane and hydrogen bonds
, everything follows its path, and the wonders of chemistry are also contained in the microscopic world. Methane ($CH_4 $) is the simplest hydrocarbon, with a stable structure, a regular tetrahedral shape of molecules, carbon atoms in the center, and four hydrogen atoms distributed at the top.
However, many substances in the world have different properties due to the existence of hydrogen bonds. Although hydrogen bonds are not traditional chemical bonds, they have a profound impact on the physical and chemical properties of substances.
Compared with methane, substances containing hydrogen bonds tend to have higher melting boiling points. Taking water as an example, hydrogen bonds between water molecules criss-cross, making water liquid at room temperature and pressure, while methane is gaseous at room temperature due to only weak van der Waals forces between molecules.
And hydrogen bonds also play a significant role in the solubility of substances. Some solutes containing hydrogen bonds are easily soluble in solvents containing hydrogen bonds. Methane is insoluble in water, because it cannot form hydrogen bonds with water molecules, and the intermolecular forces are incompatible.
Furthermore, hydrogen bonds also play an important role in biological systems. The structure and function of biological macromolecules such as proteins and nucleic acids are closely related to hydrogen bonds. Methane, on the other hand, has a low direct participation in general biological systems.
From the perspective of $CH_4 $, because of its structural characteristics, it involves very little hydrogen bonding, and is obviously different from many hydrogen-bonded substances in properties. This is one example of the influence of microstructure on macroscopic properties, from which we can see the wonderful order of the chemical world.
