Question

Flourobenzene is prepared from benzene diazonium salt. this reaction is known as

Answer 1

The reaction is khown as balz schimann reaction

Answer 2

Schiemann reaction involves the preparation of fluorobenzene from benzene diazonium salt.

• Schiemann reaction is a reaction in which an aromatic amine is converted to aryl fluoride through the formation of a diazonium salt intermediate.  
• An aromatic amine, aniline is treated with nitrous acid in presence of tetraborofluoric acid.

• The resultant intermediate, diazonium tetrafluoroborate, yields fluorobenzene on heating.
• The reaction is given below in the attachment.
