Using the concept of three-electron bond we can represent the actual electron structure of benzene and other molecules, explain specificity of the aromatic bond and calculate the delocalization energy. The aromatic bond is a three-electron bond in flat cyclic systems with a specific interaction of electrons through the cycle. In benzene formed a new type of chemical bonds – an aromatic bond, which has a multiplicity of more than 1.5 (1.66) http://vixra.org/author/bezverkhniy_volodymyr_dmytrovych
