Solution and Explanation

Conversion of Chlorobenzene to Biphenyl 

To convert chlorobenzene to biphenyl, the Wurtz-Fittig reaction is employed.

In this reaction, two molecules of chlorobenzene undergo a coupling reaction in the presence of metallic sodium and dry ether. The sodium facilitates the removal of chlorine atoms and formation of a new carbon-carbon bond between the phenyl groups, resulting in the formation of biphenyl.

Reaction Equation:

 \( 2 \ , \text{C}_6\text{H}_5\text{Cl} \xrightarrow{\text{Na , ether}} \text{C}_6\text{H}_5\text{-C}_6\text{H}_5} \)

Product: Biphenyl
