*** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available. If benzene must be used in an experiment, it should be handled at all stages in a fume cupboard.
English: VB mixing diagram of benzene. The Kekulé structures are mutually transformable by the D 6h point group operations C 2, σ v and i; a linear combination produces a ground A 1g state and the first excited B 2u state. Ref. Sason S. Shaik; Phillipe C. Hiberty (2008). A Chemist's Guide to Valence Bond Theory.

Structural diagrams of the BTX hydrocarbons. In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene , toluene , and the three xylene isomers , all of which are aromatic hydrocarbons .
Such diagrams are available in the speciality literature. [1] [2] [3] The same information can be depicted in a normal orthogonal diagram, showing only two substances, implicitly using the feature that the sum of all three components is 100 percent. The diagrams below only concerns one fuel; the diagrams can be generalized to mixtures of fuels.
A diagram of an aromatic ring current. B 0 is the applied magnetic field, the red arrow indicating its direction. The orange ring shows the direction of the ring current, and the purple rings show the direction of the induced magnetic field. An aromatic ring current is an effect observed in aromatic molecules such as benzene and naphthalene.
