Question

The conversion of benzene diazonium chloride to bromobenzene can be accomplished by reimer-tiemann reaction friedel-crafts reaction gattermann reaction azo-coupling reaction

Answer 1

Explanation:

diazonium salts react with copper powder and hydrogen to form bromobenzene. This is called Gatterman Reaction.

Answer 2

CONVERSION OF BENZENE DIAZONIUM CHLORIDE TO BROMOBENZENE IS "GATTERMANN REACTION".

Explanation:

• In gattermann reaction, first the diazonium salt of benzene is formed. Then it reacts with Cu/HBr to form bromobenzene.
• In diazotization reaction, benzene reacts with nitrous acid at 0-5 °C to form diazonium salt.
• This diazonium salt will further react with hydrobromic acid in presence of copper to form bromobenzene.
• The gattermann reaction is similar to friedel-craft's reaction.
