Question

Fluorobenzene can be synthesised in the laboratory: (A) From aniline by diazotisation followed by heating the diazonium salt with HBF 4 (B) By direct fluorination of benzene with F 2 gas (C) By reacting bromobenzene with NaF solution (D) By heating phenol with HF and KF

Tardigrade Admin · Accepted Answer

Schiemann reaction is when diazonium salt is treated with fluoroboric acid (HBF 4 ), the fluorobenzene is formed. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/85930f096549799ed01eb528bd5781d9-.png" />

Q. Fluorobenzene can be synthesised in the laboratory:

From aniline by diazotisation followed by heating the diazonium salt with $H B F_{4}$

By direct fluorination of benzene with $F_{2}$ gas

By reacting bromobenzene with $N a F$ solution

By heating phenol with $H F$ and $K F$

Schiemann reaction is when diazonium salt is treated with fluoroboric acid (HBF $_{4}$ ), the fluorobenzene is formed.
