Dipole Dipole London Dispersion Hydrogen Bonding
Between heaven and earth, all things have spirits, and the principle of their interaction is related to physical properties. Today, there are three forces, called Dipole-Dipole, London Dispersion, and Hydrogen Bonding.
The dipole force is the force between polar molecules. Polar molecules have uneven charge distribution, one end is positively charged and the other end is negatively charged. Just like there are differences between men and women, yin and yang attract each other. This force causes molecules to attract each other, affecting the boiling point, melting point and other properties of matter.
London Dispersion Force exists between all molecules. Although it is not a polar molecule, electrons are not static, and the uneven distribution of instantaneous charges can cause instantaneous dipoles. This instantaneous dipole induces neighboring molecules to produce instantaneous dipoles, resulting in mutual attraction. Although the force is weak, the accumulation of many molecules also has an important impact on the properties of matter.
The hydrogen bond force is a special dipole force. When a hydrogen atom is connected to an electronegative atom (such as nitrogen, oxygen, and fluorine), the hydrogen atom is partially positively charged, and can attract the lone pair of electronegative atoms to each other, forming a hydrogen bond. The force of hydrogen bonding is stronger than the London dispersion force, and sometimes even stronger than the general dipole force, and has a significant impact on the solubility and melting point of matter.
These three forces each have their own properties. In the microscopic world, they affect the shape and properties of matter. Although invisible and colorless, they are the root of all changes.
