Common Mistakes When Using “meta-dichlorobenzene”

  • Misspelling as 'metadichlorobenzene' (should have a hyphen).
  • Pronouncing 'benzene' as /bɛnˈzeɪn/ (incorrect) instead of /ˈbɛnziːn/.
  • Confusing its properties with the more common para-isomer.

FAQ

Frequently Asked Questions

Like many industrial organic chemicals, it can be harmful. It may be irritating, toxic if ingested or inhaled, and harmful to the environment. Always consult the specific Material Safety Data Sheet (MSDS/SDS) for proper handling.

They are isomers. The chlorine atoms are on carbon atoms 1 and 3 in the meta-isomer, and on carbons 1 and 4 (opposite) in the para-isomer. This leads to different physical properties (melting point, boiling point) and chemical reactivity.

No. It is not a consumer product. It is an industrial chemical purchased from specialist chemical suppliers for professional or research use.

The hyphen is standard in chemical nomenclature when using a positional prefix (meta-, ortho-, para-) before a compound name to indicate it is a specific isomer. It clarifies that 'meta-' modifies 'dichlorobenzene'.

A chemical compound, specifically an isomer of dichlorobenzene where the two chlorine atoms are positioned at the 1 and 3 carbon atoms on the benzene ring.

Meta-dichlorobenzene is usually technical/scientific in register.

Meta-dichlorobenzene: in British English it is pronounced /ˈmɛtə daɪˌklɔːrəʊˈbɛnziːn/, and in American English it is pronounced /ˈmɛtə daɪˌklɔːroʊˈbɛnziːn/. Tap the audio buttons above to hear it.

Memory Aids

Mnemonic

Think: 'META' means 'middle' in Greek. In 'meta-dichlorobenzene', the chlorine atoms are separated by one carbon, like they're not neighbours but also not opposite—they're in a middle relationship on the benzene ring.
