Concept:The reaction of two aryl halide molecules with sodium metal in dry ether to form a diaryl compound is called the Fittig reaction.Explanation:In this reaction, an aryl halide reacts with sodium metal in dry ether.Two aryl radicals combine to form a symmetrical diaryl compound, such as biphenyl.The general equation is:$$2\,\mathrm{Ar}-\mathrm{X} + 2\,\mathrm{Na} \xrightarrow[\text{dry ether}]{} \mathrm{Ar}-\mathrm{Ar} + 2\,\mathrm{NaX}$$For example, when bromobenzene is treated with sodium in dry ether, biphenyl is obtained:$$2\,\mathrm{C_6H_5Br} + 2\,\mathrm{Na} \xrightarrow[\text{ether}]{\text{dry}} \mathrm{C_6H_5-C_6H_5} + 2\,\mathrm{NaBr}$$The Wurtz reaction involves alkyl halides, not aryl halides.The Wurtz-Fittig reaction uses a mixture of an aryl halide and an alkyl halide.Hence, the given reaction is specifically the Fittig reaction.Answer:Option C.
