Question

write a note on hoffmann bromamide degradation​

Answer 1

Answer:

What Is Hoffmann bromamide Reaction? When an amide is treated with bromine in an aqueous or ethanolic solution of sodium hydroxide, degradation of amide takes place leading to the formation of primary amine. This reaction involving degradation of amide and is popularly known as Hoffmann bromamide degradation reaction.

Answer 2

Answer :-

In Hoffmann bromamide degradation reaction, an amide reacts with bromine and aqueous solution of sodium hydroxide which produces primary amine. This a degradation reaction as primary amine in the product has one carbon lesser than primary amide (in the reactant).

Secondary and tertiary amides don’t show Hoffmann bromamide reaction. Only one unit or molecule of bromine is used in the reaction.

Primary amides show this reaction.
