Vedclass · Answer

(A) The conversion of aniline to chlorobenzene is a two-step process known as the Sandmeyer reaction. Step $1$: Aniline $(C_6H_5NH_2)$ reacts with $NaNO_2 / HCl$ at a low temperature of $273-278 \ K$ $(0-5 \ ^\circ C)$ to form benzene diazonium chloride $(C_6H_5N_2^+Cl^-)$. Step $2$: The benzene diazonium chloride is then treated with cuprous chloride $(Cu_2Cl_2)$ in the presence of $HCl$ to yield chlorobenzene $(C_6H_5Cl)$ and nitrogen gas $(N_2)$. Therefore,the correct set of reagents is $NaNO_2 / HCl, 273-278 \ K ; Cu_2Cl_2 / HCl$.

Which of the following sets of reagents convert aniline to chlorobenzene?
