Substitution Reactions of Benzene and Other Aromatic Compounds

Substitution Reactions of Benzene and Other Aromatic Compounds. The remarkable stability of the unsaturated hydrocarbon benzene has been discussed in an earlier section.The chemical reactivity of benzene contrasts with that of the alkenes in that substitution reactions occur in preference to addition reactions, as illustrated in the following diagram (some comparable reactions of cyclohexene

Ortho, Meta, and Para in Organic Chemistry

The terms ortho, meta, and para are prefixes used in organic chemistry to indicate the position of non-hydrogen substituents on a hydrocarbon ring (benzene derivative). The prefixes derive from Greek words meaning correct/straight, following/after, and similar, respectively. Ortho, meta, and para historically carried different meanings, but in 1879 the American Chemical Society settled upon
