Question

Compounds that give aromatic salt on reaction with 4

Answer 1

Schiemann reaction – a diazonium salt reacts with fluoroboric acid (HBF4) to form aryl fluoride. This is a useful reaction because acyl fluoride cannot be produced by direct fluorination because F2 reacts too violently. 4. Synthesis of benzene – a diazonium salt reacts with hypophosphorous acid (H3PO2) to form benzene.
