Vedclass · Answer

(C) The synthesis of bromobenzene from benzene diazonium salts is a classic example of the Sandmeyer reaction.In this reaction,the benzene diazonium salt is treated with cuprous bromide $(Cu_2Br_2)$ in the presence of hydrobromic acid $(HBr)$.The reaction proceeds as follows:$C_6H_5N_2^+Cl^- + Cu_2Br_2 \xrightarrow{HBr} C_6H_5Br + N_2 + Cu_2Cl_2$Thus,the presence of $Cu_2Br_2$ and $HBr$ is required.

Presence of which of the following is suitable for the synthesis of bromobenzene from benzene diazonium salts?
