What Is Hydrogen Bonding In Chemistry
On the chemical nature of hydrogen bonding
The formation of human matter depends on the bond. Bonding is the interaction between atoms. Among all bonds, hydrogen bonds are unique. Although they are not traditional strong bonds, they have far-reaching effects on chemical things.
The so-called hydrogen bond is a weak interaction between a hydrogen atom and a highly electronegative atom (such as fluorine, oxygen, and nitrogen) after covalently binding, and another atom with strong electronegativity. The hydrogen atom is like a bridge connecting two strongly electronegative atoms. For example, in water ($H_2O $), hydrogen is covalently connected with oxygen, and hydrogen in a water molecule can form a hydrogen bond with oxygen in other water molecules. The origin of the hydrogen bond is due to the characteristics of the hydrogen atom. The hydrogen atom has only one electron. When it binds to a strong electronegative atom, the electron cloud is biased towards the atom, causing the hydrogen nucleus to be nearly exposed. This exposed hydrogen nucleus is easily attracted by the lone pair of electronegative atoms of other strong electronegative atoms, so it forms a hydrogen bond.
The force of hydrogen bonding is weaker than that of covalent bonds and ionic bonds, but its effect is significant. It has a huge impact on the physical properties of substances. For example, the melting boiling point of hydrogen bonds is often higher than that of similar non-hydrogen bonds. The melting boiling point of water is different from that of hydrogen sulfide ($H_2S $), because there are hydrogen bonds between water molecules. To make its phase transition, more energy is required to break the hydrogen bond.
Furthermore, in biological systems, hydrogen bonds are also crucial. The secondary structure of proteins, the formation of alpha-helix and beta-fold, all depend on hydrogen bonds. DNA double helix structure, base pairing is also maintained by hydrogen bonds, which ensures the stable transmission of genetic information.
In summary, although hydrogen bonds are small, they play an extraordinary role in various fields of chemistry and biology. Exploring the mystery of hydrogen bonds can provide key evidence for the development of various disciplines, and open up new avenues for the journey of science.
