Hydrogen Bonds Simple Definition
Hydrogen is the smallest atom, and its bond is also the force of chemistry. The bond of hydrogen, in short, is the hydrogen atom in the intermolecular or intramolecular with strong electronegativity atoms, such as oxygen, nitrogen, fluorine, etc., with a weak force. Although this force is weak, it has a huge impact on the properties of many substances, such as boiling point, melting point, solubility, etc.
When a hydrogen atom has only one electron, when it is connected to an electronegativity strong, the electron cloud is biased to it, causing the hydrogen atom to be partially positive, so it can attract the electronegativity strong atom with the adjacent lone pair of electrons with an electrostatic attractive force. This attractive force is the bond of hydrogen.
In water, water molecules are linked by hydrogen bonds, so water has a higher boiling point and melting point, and can dissolve many substances, relying on the power of hydrogen bonds. And in biological macromolecules, such as proteins, nucleic acids, etc., hydrogen bonds are also important for maintaining their structure and function. The secondary structure of proteins, α-helix and β-fold, are all formed by hydrogen bonds; the base pairing of nucleic acids also relies on hydrogen bonds to ensure their stability.
Although the bond of hydrogen has a small force, it plays a huge role in various fields such as chemistry and biology. It is related to the state and nature of matter, as well as the mystery of life. It is also an important part of chemical research.
