Vedclass · Answer

(D) Fluorobenzene is prepared by the Balz-Schiemann reaction. In this process,aniline is first converted to benzene diazonium chloride using $NaNO_2$ and $HCl$ at $0-5^{\circ}C$. Then,it is treated with fluoroboric acid $(HBF_4)$ to form benzene diazonium tetrafluoroborate $(C_6H_5N_2^+BF_4^-)$. Finally,heating this salt leads to the formation of fluorobenzene,$BF_3$,and $N_2$ gas.
