Identify the name of reaction that of aryl halide with alkyl halide and sodium metal in dry ether to give substituted aromatic compounds.

Options

  1. AWurtz reaction
  2. BFittig reaction
  3. CWurtz-Fittig reaction
  4. DFriedel Crafts reaction

Correct answer

C. Wurtz-Fittig reaction

Step-by-step solution

The reaction involves coupling an aryl halide with an alkyl halide using sodium in dry ether to yield an alkyl-aryl product. The Wurtz-Fittig reaction is defined by Ar-X + R-X + 2Na dry ether Ar-R + 2NaX , matching the given transformation. Other reactions do not fit: the Wurtz reaction couples two alkyl halides ( R-R' ), the Fittig reaction couples two aryl halides ( Ar-Ar' ), and the Friedel-Crafts reaction uses Lewis acid catalysis rather than sodium metal.
