Vedclass · Answer

(A) The chemical equation for the Hoffmann bromamide degradation reaction is: $RCONH_{2} + Br_{2} + 4NaOH \rightarrow RNH_{2} + Na_{2}CO_{3} + 2NaBr + 2H_{2}O$.$(A)$ is correct because the stoichiometry of the reaction requires $4$ moles of $NaOH$ and $1$ mole of $Br_{2}$ for every mole of primary amide.$(B)$ is false because alkyl amides (primary amides) readily undergo this reaction.$(C)$ is correct because this reaction is a standard laboratory method for the synthesis of primary amines.$(D)$ is false because secondary amides $(RCONHR')$ lack the necessary $-NH_{2}$ group required for the rearrangement mechanism.$(E)$ is correct because the by-products formed are indeed $Na_{2}CO_{3}$,$NaBr$,and $H_{2}O$.
