Question

Flourobenzene $\left(C_6{H}_{5}F\right)$ can be synthesized in the laboratory:

• A. By heating phenol with $HF$ and $KF$.
• B. By reacting bromobenzene with $NaF$ solution.
• C. By direct flourination of benzene with $F_2$ gas.
• D. From aniline by diazotization followed by heating the diazonium salt with $HB{F}_4$.

Answer 1

The correct option is D From aniline by diazotization followed by heating the diazonium salt with $HB{F}_4$.

Flourobenzene $\left(C_6{H}_{5}F\right)$ can be synthesized in the laboratory followed by heating the diazonium salt with $HB{F}_4$.
Hence, option (b) is the answer.
