The reaction of bromobenzene with bromomethane and sodium metal in dry ether to give toluene is

  • A
    Wurtz reaction
  • B
    Fittig reaction
  • C
    Friedel crafts reaction
  • Correct answer
    D
    Wurtz-fittig reaction

Solution

The reaction involves an aryl halide and an alkyl halide reacting with sodium metal in dry ether to produce an alkylbenzene, which characterizes the Wurtz-Fittig reaction.

The general form is $Ar-X + R-X + 2Na \xrightarrow{\text{dry ether}} Ar-R + 2NaX$.

For bromobenzene and bromomethane, the reaction is $C_6H_5Br + CH_3Br + 2Na \xrightarrow{\text{dry ether}} C_6H_5CH_3 + 2NaBr$.

This distinguishes it from the Wurtz reaction (two alkyl halides), the Fittig reaction (two aryl halides), and the Friedel-Crafts reaction (uses Lewis acid catalyst, not sodium metal).

The correct identification is $\boxed{D}$.

Hence, the correct answer is option: 'D'.
