Benzene is an important organic chemical compound with the chemical formula C 6 H 6. Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom.Because its molecules contain only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.he most common reactions of benzene involve substitution of a proton by other groups. Electrophilic aromatic substitution is a general method of derivatizing benzene. Benzene is sufficiently nucleophilic that it undergoes substitution by acylium ions and alkyl carbocations to give substituted derivatives.
