Solution

Hoffmann Bromamide Degradation reaction is shown by \[\ce{ArCONH2}\].

Explanation:

Hoffmann invented a method for producing primary amines by treating an amide with bromine in an aqueous or ethanolic sodium hydroxide solution. An alkyl or aryl group migrates from the amide's carbonyl carbon to the nitrogen atom during this degradation reaction.

\[\ce{C4H5CONH2 ->[Br2 + NaOH] C4H5NH2}\]
