Vedclass · Answer

(B) Fluorobenzene is prepared in the laboratory using the $Schiemann$ reaction. First,aniline is converted to benzene diazonium chloride via diazotization. Then,it is treated with fluoroboric acid $(HBF_4)$ to form benzene diazonium fluoroborate $(C_6H_5N_2BF_4)$. Finally,heating this salt causes its decomposition to yield fluorobenzene,$N_2$,and $BF_3$.
