About Benzene
Formula structure C6 H6 Molar mass 78.1121g/mol

Physical Properties
Melting point 5.5c(278.6k) Boiling point 80.1c(353.2k) Density 0.8786g/cm3, liquid Natural state-colorless liquid Dissolves slightly in water and floats on top of water = = =History= Michael Faraday found Benzene in 1825. He obtained the bezene from a oily film that is usually found in gas and crude oil. This acidic material was derived from benzoin by sublimation and named "flowers of benzoin," of benzoic acid. The hydrocarbon derived from benzoic acid which came the name benzin, benzol, or benzene. Having benzene in your system can cause you to get cancer. Benzene is also used in cigarettes, soda, plastics, rubbers, drugs, detergents, and nylon. media type="custom" key="265641" =Structure= Mass percent of carbon 92.24% Mass percent of hydrogen 7.76% Percent composition by number 50% carbon and 50% hydrogen It is a parent compound of all aromatic compounds. It is a hexagon with its points representing each of the six carbon atoms. Each carbon atom is bonded to its neighbor with one electron from each atom. Since each atom has two neighbors this uses two electrons from each atom. = = =Chemical Properties= It reacts with Bromine to form bromobenzene It reacts with concentrated sulfuric acid at room temperture which produces benzenesulfonic acid. Reacts with Methyl to form Methylbenzene Chlorination reacts with benzene and they are the most halogenation reactions.

Uses and Importance of the Compound
The main use of benzene is for the production of other chemicals. Benzene's use has been regulated in order to protect the public from exposure to its dangerous levels. The attempt to keep it away from people is conflicted because it is found in everyday products. They can produce cancer cells. It has been used for a varitey of industrial and commerical purposes.
