Chemistry Notes Benzene

introduction
Benzene is an organic compound with molecular formula C6H6. Benzene molecule is made of six carbon atoms joined in a ring, with one H-atom attached to each C-atom. Because of its molecules contain only carbon and hydrogen atoms, benzene is also known as a hydrocarbon.
it is a natural constituent of crude oil, it is an aromatic hydrocarbon, having cyclic hydrocarbon with a continuous pi bond. It is abbreviated as Ph–H. Benzene is a colourless and a highly flammable liquid having a sweet smell. It is mostly used as a precursor to heavy chemicals, like ethylbenzene & cumene, which produced on a billion kilogram scale. Because of  having a high octane number, it is an important component of gasoline, containing a few percent of its mass. Most of its non-industrial applications have been limited because of benzene's carcinogenicity.
