WebBenzene weighs 0.87865 gram per cubic centimeter or 878.65 kilogram per cubic meter, i.e. density of benzene is equal to 878.65 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure . WebIt produces only one mono-substituted derivative, which indicates that all its six carbon and hydrogen atoms are equivalent. On the basis of these facts, in 1865 August Kekule proposed the structure of Benzene in which the six carbon atoms were arranged to form a hexagonal ring with each carbon atom carrying one hydrogen atom.
