Which of the following types of reactions is used to prepare Alkyl benzene?

Options

  1. ASwartz reaction
  2. BSandmeyer reaction
  3. CFinkelstein reaction
  4. DWurtz Fittig reaction

Correct answer

D. Wurtz Fittig reaction

Step-by-step solution

The Wurtz-Fittig reaction involves the reaction of an aryl halide with an alkyl halide in the presence of sodium metal and dry ether to form an alkyl benzene. C₆H₅X + RX + 2Na dry ether C₆H₅R + 2NaX Swartz reaction is used for the synthesis of alkyl fluorides. Sandmeyer reaction is used to synthesize aryl halides from aryl diazonium salts. Finkelstein reaction is used for the preparation of alkyl iodides from alkyl chlorides or bromides. Answer: Wurtz Fittig reaction
