$Ar{N}_2^{+}C{l}^{-}\to ArF$

• A. $\text{Only}HB{F}_4$
• B. $HF$
• C. $F_2$
• D. $HB{F}_4/\text{Heat}$

Answer 1

The correct option is D $HB{F}_4/\text{Heat}$

Balz Schiemann reaction mechanism details the preparation and subsequent thermal decomposition of an aromatic fluoroborate to give the corresponding aryl fluoride. The reaction gets its name from the German scientists – Günther Schiemann and Günther Balz.
