Easy Definition Of Hydrogen Bonding
Hydrogen is light and pure gas. The simple meaning of hydrogen bond is the interaction between hydrogen atoms and atoms with large electronegativity and small radius (such as fluorine, oxygen, nitrogen, etc.) in molecules or within molecules by electrostatic attractive force. Although this attractive force is weaker than the chemical bond, it has a huge impact on the physical and chemical properties of the substance.
When a hydrogen atom bonds with a large electronegativity atom, its electron cloud is biased towards the atom, causing the hydrogen nucleus to be slightly exposed and partially positively charged. At this time, there are atoms with large electronegativity and lone pairs of electrons nearby, and electrostatic attraction occurs between the two, which is a hydrogen bond.
Looking at the properties of water, due to the existence of hydrogen bonds, its boiling point and melting point are different from common sense, and the density change is also unique. In many organic substances, hydrogen bonds also affect their molecular configuration and solubility. This is the manifestation of hydrogen bonds in the physical properties of the state, which cannot be ignored.
