The number of chemical structures which include the benzene ring are almost immeasurable.
Hoffman isolated the same product, later called benzene, in large quantities by distilling coal. Benzene is a colorless, flammable liquid with a sweet odor. Cigarette smoke is a major source of benzene exposure. There is much less evidence linking benzene to any other type of cancer.
Other uses include the preparation of aniline for dyes and dodecylbenzene for detergents. The structure of benzene has been of interest since its discovery.
Discovery of benzene Benzene was first discovered by the English scientist Michael Faraday in in illuminating gas. People can be exposed to benzene: High levels of exposure can cause both short-term and long-term health effects. Benzene is also a natural part of crude oil and gasoline and therefore motor vehicle exhaustas well as cigarette smoke.
See Article History Benzene C6H6simplest organic, aromatic hydrocarbon and parent compound of numerous important aromatic compounds.
Benzene is one of the first chemicals in history whose unique properties were studied by chemists.
A substance that causes cancer or helps cancer grow is called a carcinogen. The principal commercial uses for benzene, at present, include the manufacture of ethylbenzene, cumene and cyclohexane. Out of mere curiosity, he set it alight and the gas burned.
Workplace exposures Workers in industries that make or use benzene may be exposed to this chemical. If you are a smoker, try to quit. If you are concerned about benzene, there are several ways you can limit your exposure.
Benzene is also commonly chlorinated to yield various chlorobenzenes, put to use in such products as moth flakes, or alkylated to produce alkylbenzenes, used to manufacture various detergent products.
The link between benzene and cancer has largely focused on leukemia and other cancers of blood cells. How are people exposed to benzene?
The long battle to discover the true structure of benzene ended in This innovation suggested that benzene contained delocalized electrons as shown in the diagram.
Furthermore, this hybridization in benzene makes the molecule more stable than it would be if it had localized bonds. When possible, limiting the time you spend near idling car engines can help lower your exposure to exhaust fumes, which contain benzene as well as other potentially harmful chemicals.
It is used mainly as a starting material in making other chemicals, including plastics, lubricants, rubbers, Benzene essay, detergents, drugs, and pesticides.
Several government agencies regulate benzene levels and exposures. The bibliography has been excluded. Faraday probably had no idea that his "bicarburet of hydrogen" would long remain an enigma to chemists. In German chemist A. In studies done in the lab, animals are exposed to a substance often in very large doses to see if it causes tumors or other health problems.Free Essay: 1.
