Benzene, a constituent of crude oil, is an organic chemical compound its molecular formula is c 6 h 6it contains six carbon and hydrogen atoms each. Benzene is a hugely important compound in organic chemistry it consists of six carbon atoms joined together in a ring, with a hydrogen atom bonded to each carbon by replacing one or more of these hydrogens with a functional group, a large number of different compounds can be formed. The word organic means something very different in chemistry than it does when you're talking about produce and food organic compounds and inorganic compounds form the basis of chemistry the primary difference between organic compounds and inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not contain carbon.

Benzene is the parent substance of the aromatic compounds, a large and important group of organic compounds it is the first of a series of hydrocarbons known as the benzene series, formed by the substitution of methyl groups, ch 3 , for the hydrogen atoms of the benzene molecule.
Chemical classification: hydrocarbons (contain hydrogen and carbon atoms), volatile organic compounds summary: benzene is a colorless liquid with a sweet odor it evaporates into the air very quickly and dissolves slightly in water it is highly flammable and is formed from both natural processes and human activities. Benzene is an important organic chemical compound with the chemical formula #c_6h_6# human exposure to benzene has been associated with a range of acute and long-term adverse health effects and diseases, including cancer and aplastic anaemia. Volatile organic compounds, or vocs are organic chemical compounds whose composition makes it possible for them to evaporate under normal indoor atmospheric conditions of temperature and pressure 3 this is the general definition of vocs that is used in the scientific literature, and is consistent with the definition used for indoor air quality.

1 benzene and aromatic compounds • benzene (c 6h 6) is the simplest aromatic hydrocarbon (or arene) • benzene has four degrees of unsaturation, making it a highly unsaturated hydrocarbon • whereas unsaturated hydrocarbons such as alkenes, alkynes and dienes readily undergo addition reactions, benzene does not. Benzene (which is the name that was given to the aromatic compound c 6 h 6) is probably the most common and industrially important aromatic compound in wide use today it was discovered in 1825 by michael faraday, and its commercial production from coal tar (and, later on, other natural sources) began in earnest about twenty-five years later. To address this need, benzene and volatile organic compound (voc) emissions within a major chemical plant/refinery were measured and compared with emission factor estimates the results of this study indicate estimated emissions were never higher and commonly lower than the measured emissions.
