Vedclass · Answer

(B) Direct fluorination of benzene is highly exothermic and difficult to control,often leading to explosive reactions or polyfluorinated products. The $Balz-Schiemann$ reaction is the most effective method for introducing a fluorine atom into the benzene ring. In this process,an aniline is converted into a benzene diazonium tetrafluoroborate salt $(C_6H_5N_2^+BF_4^-)$ by reaction with $NaNO_2/HCl$ followed by $HBF_4$. Upon heating,the salt decomposes to yield fluorobenzene,$N_2$ gas,and $BF_3$.

The best method to introduce fluorine in the benzene ring as a substituent is:
