Question

Fittig reaction can be used to prepare ___________. *
Toluene
Acetophenon
Biphenyl
Chlorobenzene

Answer 1

Answer:

Wurtz – Fittig reaction is best for formation of asymmetrical products if halide reactants are different in their relative chemical reactivities. The reaction is basically used for alkylation of aryl halides, but it can be used for production of biphenyl compounds by the use of ultrasound.

Answer 2

Answer:

Fittig reaction can be used to prepare Biphenyl.

Explanation:

Wurtz - Fittig reaction : In this reaction , an aryl halide reacts with another aryl halide or alkyl halide in the presence of Sodium in dry ether as a catalyst.

In order to prepare biphenyl using the Wurtz-Fittig reaction , chlorine reacts with Benzene to form chlorobenzene in the presence of anhydrous aluminium chloride to form chloro benzene . Further, chloro benzene in the presence of Sodium (Na) in dry ether forms diphenyl.

The reaction involved in the processs is gven below:

                        C6H6 + Cl2  ------>    AlCl3Ph−Cl + HCl  

                   2Ph−Cl  + 2Na     -------> dry etherPh−Ph+2NaCl

So, the correct option is C : Biphenyl.
