Chemical bond, structure and properties of the substance.
Interactions that result in the unification of chemical particles into substances are usually divided into chemical and intermolecular bonds. The first group, in turn, is divided into ionic, covalent and metallic bonds.
An ionic bond is a bond of differently charged ions. Such a connection arises due to electrostatic attraction. In order for an ionic bond to form, the ions must be of different sizes. This is due to the fact that ions of a certain size tend to give up electrons, while others tend to accept them.

Covalent bonding occurs due to the formation of a common pair of electrons. For its occurrence, it is necessary that the radius of the atoms be the same or similar.
The metallic bond arises due to the generalization of valence electrons. It is formed if the size of the atoms is large. Such atoms usually give up electrons.
According to the type of structure, all substances can be divided into molecular and non-molecular. Most organic substances belong to the first type. According to the type of chemical bond, substances with covalent, ionic and metallic bonds are distinguished.
The main provisions of the theory of the chemical structure of organic substances.
Butlerov's theory is the scientific foundation of all organic chemistry. Based on its main provisions, Butlerov gave an explanation of isomerism, which subsequently helped him to discover several isomers.
According to the theory of the chemical structure of organic substances, the connection of atoms in molecules is strictly ordered. It occurs in a certain sequence (depending on the valence of the atoms). The sequence of interatomic bonds is commonly called the chemical structure of a molecule.
Another important provision of this theory is the possibility of using various chemical methods to determine the structure of a substance.
Groups of atoms in a molecule are interconnected and affect each other. The basic properties of a substance, according to this theory, are determined by its chemical structure.
