Fradel crafts reaction?explain.

Answer»
  • In this reaction, alkyl or acyl groups are added to a benzene ring using a Lewis acid.
  • Acylation is the term given to SUBSTITUTING an acyl group such as CH3CO- into another molecule

It is an electrophilic aromatic substitution reaction in which a carbocation attacks an aromatic ring with the NET result that one of the aromatic protons is replaced by an alkyl group.

  • It activates the arene substrate, polyalkylation may occur.

As one of the most IMPORTANT reactions in aromatic substitution chemistry, the Friedel-Crafts reaction receives extensive coverage in sophomore ORGANIC chemistry.

The most widely used Lewis acid for the Friedel-Crafts reactiuon is aluminum chloride
