chlorobenzene
A chemist carefully pours chlorobenzene from a labeled glass bottle into a beaker.
Noun: 1. A colorless, volatile, flammable liquid with an almond-like odor: Chlorobenzene is an organic compound synthesized from chlorine and benzene. Its primary characteristics include being colorless, easily evaporating (volatile), and capable of catching fire (flammable). It possesses a distinct smell reminiscent of almonds. 2. An industrial chemical used as a solvent and precursor: It is primarily utilized in industrial settings as a solvent for various materials and as a starting material (precursor) in the manufacture of other important compounds, such as phenol, DDT, and numerous other organic chemicals.
- As a specific chemical compound:
- The laboratory synthesized chlorobenzene for the upcoming experiment.
- The characteristic almond odor of chlorobenzene is noticeable in small quantities.
- In an industrial or historical context:
- For many years, chlorobenzene was a key intermediate in the production of DDT.
- This reaction requires chlorobenzene as a solvent to proceed efficiently.
- In chemical nomenclature and processes: The term is used precisely to denote the monosubstituted derivative where one chlorine atom is attached to a benzene ring (C₆H₅Cl). It is a classic example of an aryl halide and is often discussed in contexts of electrophilic aromatic substitution reactions.
- The nitration of chlorobenzene requires careful control of reaction conditions.
- Dichlorobenzene (n): An organic compound with two chlorine atoms substituted on the benzene ring (e.g., 1,2-dichlorobenzene, 1,4-dichlorobenzene, used as a deodorant and pesticide).
- Chlorinated hydrocarbon (n): A broader class of compounds to which chlorobenzene belongs, consisting of hydrocarbons where one or more hydrogen atoms are replaced by chlorine.
- Monochlorobenzene (n): A more systematic chemical name, explicitly indicating one chlorine substituent.
- Phenyl chloride (n): An alternative historical name for the same compound.
- Chlorobenzene production/manufacture: Refers to the industrial process of making the compound.
- Chlorobenzene derivative: Refers to a more complex chemical compound made from or related to chlorobenzene.
- Using chlorobenzene as a solvent: A common phrase describing one of its primary applications.

- a colorless volatile flammable liquid with an almond odor that is made from chlorine and benzene; used as a solvent and in the production of phenol and DDT and other organic compounds
