The structure of benzene was determined many years ago, by a chemist called Kekule. The structure consists of 6 carbon atoms in a hexagonal ring, with alternating single and double carbon-carbon bonds. This suggests that benzene should react in the same way that an unsaturated alkene does. However, this is not the case. bud light and budweiser alcohol content

"WebBenzene is composed of six carbon and six hydrogen atoms. It contains three double bonds that are alternate to each other. There are mainly three factors that decide the overall stability of benzene over other organic compounds. These factors are as follows: Resonance energy. Aromatic stability. Structural stability.
