Vedclass · Answer

(A) The given reaction is an example of the Ullmann reaction. In the Ullmann reaction,an aryl halide (like $p$-iodotoluene) reacts with copper powder upon heating to form a biaryl compound. Two molecules of $p$-iodotoluene react with $Cu$ to form $4,4'$-dimethylbiphenyl and $CuI_2$ (or $CuI$ depending on stoichiometry). The reaction is: $2 CH_3-C_6H_4-I + Cu \xrightarrow{\Delta} CH_3-C_6H_4-C_6H_4-CH_3 + CuI_2$. Thus,the product is $4,4'$-dimethylbiphenyl.
