what difference between sandmeyer and balz sheiman reaction?

Asked by gargimoitreyee 17th March 2018, 10:46 AM

Answer:

Sandmeyer’s reaction

 When a primary aromatic amine, dissolved or suspended in cold aqueous mineral

acid, is treated with sodium nitrite, a diazonium salt is formed.

Mixing the solution of freshly prepared diazonium salt with cuprous chloride or

cuprous bromide results in the replacement of the diazonium group by –Cl or –Br.

Balz-Schiemann Reaction:

The conversion of aryl amines to aryl fluoride via formation of diazonium fluoroborates.

This reaction involves the replacement of the diazonium group by –F.
