JEE Main 2026 — Amines Question with Solution

The balanced chemical equation for Hoffmann bromamide degradation is:

${\text{R-CONH}}_2+{\text{Br}}_2+4\text{NaOH}\to {\text{R-NH}}_2+{\text{Na}}_2{\text{CO}}_3+2\text{NaBr}+2{\text{H}}_2\text{O}$

Statement A is false because $1$ mole of ${\text{Br}}_2$ and $4$ moles of $\text{NaOH}$ are consumed per mole of amide.

Statement B is false because primary alkyl amides readily undergo this reaction.

Statement C is true as the primary product of this reaction is a primary amine.

Statement D is false because the reaction is strictly given by primary amides (${\text{R-CONH}}_2$), not secondary amides.

Statement E is true as the by-products formed are ${\text{Na}}_2{\text{CO}}_3$, $\text{NaBr}$, and ${\text{H}}_2\text{O}$.

Therefore, only statements C and E are true.

Answer: C and E only
