Answer 1

Balz-Schiemann’s reaction: In this reaction, aniline is first converted to benzene diazonium fluoroborate which on heating gives fluorobenzene.

\[\ce{\underset{\text{Aniline}}{C6H5NH2} ->[NaNO2/HBF4][273-278K]\underset{\text{Benzenediazonium Fluoroborate}}{C6H5N2BF4}->[\Delta]\underset{\text{Fluorobenzene}}{C6H5F + N2} + BF3}\]
