context_page_description: In the context of organic molecules, aryl is any functional group or substituent derived from an aromatic ring, usually an aromatic hydrocarbon, such as phenyl and naphthyl. "Aryl" is used for the sake of abbreviation or generalization, and "Ar" is used as a placeholder for the aryl group in chemical structure diagrams.
  A simple aryl group is phenyl, a group derived from benzene. Examples of other aryl groups consist of:
  The tolyl group, CH₃C₆H₄, which is derived from toluene
  The xylyl group, (CH₃)₂C₆H₃, which is derived from xylene
  The naphthyl group, C₁₀H₈, which is derived from naphthalene
  Arylation is the process in which an aryl group is attached to a substituent. It is typically achieved by cross-coupling reactions.

  A simple aryl group is phenyl (with the chemical formula C₆H₅), a group derived from benzene. Examples of other aryl groups consist of:
  The tolyl group, CH₃C₆H₄, which is derived from toluene (methylbenzene)
  The xylyl group, (CH₃)₂C₆H₃, which is derived from xylene (dimethylbenzene)
  The naphthyl group, C₁₀H₈, which is derived from naphthalene
  Arylation is the process in which an aryl group is attached to a substituent.  It is typically achieved by cross-coupling reactions.
