Which of the following organic compounds is a benzenoid?

Key Points

• Aniline is a benzenoid compound, as it contains a benzene ring in its structure.
• Benzenoid compounds are aromatic compounds that feature at least one benzene ring.
• In contrast, acetaldehyde, propane, and hexane are not benzenoid compounds as they do not contain a benzene ring.
• Aniline, with the chemical formula C₆H₅NH₂, is an aromatic amine and a key starting material in the manufacture of dyes, drugs, and plastics.

Additional Information

• Benzene is the simplest aromatic hydrocarbon and a precursor to many other aromatic compounds.
• Organic compounds are classified as aromatic if they follow the Hückel’s rule, which states that the compound must have a planar ring of continuously overlapping p-orbitals and 4n+2 π-electrons.

1. Aniline is synthesized industrially by the reduction of nitrobenzene or by the amination of chlorobenzene.

• Due to its aromatic nature, aniline undergoes electrophilic substitution reactions, which are typical of benzene derivatives.
