Vedclass · Answer

(D) The Hoffmann bromamide degradation reaction is used to prepare primary amines by treating an amide with bromine in an aqueous or ethanolic solution of sodium hydroxide. In this reaction,the carbonyl carbon of the amide is removed as a carbonate,and the alkyl or aryl group migrates to the nitrogen atom. As a result,the amine formed contains one carbon atom less than the starting amide. To obtain pentanamine $(C_5H_{11}NH_2)$,which has $5$ carbon atoms,the starting amide must have $6$ carbon atoms,which is hexanamide $(CH_3CH_2CH_2CH_2CH_2CONH_2)$. The reaction is: $CH_3CH_2CH_2CH_2CH_2CONH_2 + Br_2 + 4NaOH \rightarrow CH_3CH_2CH_2CH_2CH_2NH_2 + 2NaBr + Na_2CO_3 + 2H_2O$
