Abstract:
The article discusses the general formula of aromatic hydrocarbons Benzene, the first and simplest representative of aromatic hydrocarbons, was discovered in 1825 by the English chemist M. Faraday by liquefying illuminating gas (acetylene) under pressure and at low temperature. In 1931, the German chemist E. Hückel developed a quantum chemical approach to explaining aromaticity. This approach is still used today and is called the Hückel molecular orbital method. According to this approach, aromatic substances are cyclic compounds corresponding to the formula 4n+2, formed by conjugated (delocalized) π- and σ-bonds with all C atoms in the plane.
