Explain The Hydrogen Bonding
The analysis of hydrogen bonds
The hydrogen bond is also an important part of chemistry. Its formation originates from the relationship between hydrogen ions and electronegative giant atoms (such as fluorine, oxygen, and nitrogen), and the weak interaction with other electronegative giant atoms.
Hydrogen atoms, the electron cloud is often biased towards atoms with high electronegativity, causing hydrogen atoms to be naked and protons outside, in a state of positive electronegativity. Atoms with high electronegativity and lone pairs of electrons attract naked protons, which is the basis of hydrogen bonds.
The force of hydrogen bonds is weaker than that of covalent bonds, but it has a huge impact on the properties of matter. For example, in water, due to the existence of hydrogen bonds, its boiling point is extremely high, which is higher than that of hydrogen sulfide equivalent group compounds. The hydrogen bonds between the caps and the water are intertwined, and in order to vaporize the water, many hydrogen bonds need to be broken, so more energy is required.
And in biological systems, hydrogen bonds are also crucial. The secondary structure of proteins, alpha-helix and beta-fold, depend on hydrogen bonds to maintain their shape. The base pairs of nucleic acids are also matched by hydrogen bonds to ensure the quasi-transmission of genetic information.
From this perspective, although hydrogen bonds are small, they are key in the fields of chemistry and biology, and they are cardinals who control the properties of matter and the process of life.
