Basic introduction of benzene

Benzene (benzene, C6H6) organic compounds, is the composition of the most simple aromatic hydrocarbons, at room temperature for a colorless, sweet transparent liquid, its density is less than water, with a strong aromatic odor. Combustible, toxic, IARC Class I carcinogens. Benzene is insoluble in water, soluble in organic solvents, itself can also be used as organic solvents. The chemical bond between carbon and carbon is between the single bond and the double bond, which is called the large π bond, and therefore has the properties of saturated hydrocarbon substitution reaction and the nature of the unsaturated hydrocarbon addition reaction. The nature of benzene is easy to replace, difficult to oxidize, difficult to add. Benzene is a basic raw material for petrochemicals. Benzene production and production of technical level is one of the national petrochemical development level of one of the signs. Benzene has a ring called benzene ring, is the most simple aromatic ring. The structure of the benzene molecule after removing a hydrogen is called phenyl and is represented by Ph. Thus benzene can also be expressed as PhH.
