JEE Main 2026 Chemistry question
Which statements are True? A. In Hoffmann bromamide degradation, 4 moles of NaOH and 2 moles of Br₂ are consumed per mole of an amide B. Hoffmann bromamide reaction is not given by alkyl amides. C. Primary amines can be synthesized by Hoffmann bromamide degradation. D. Secondary amide on reaction with Br₂ and NaOH will give secondary amine. E. The by-products of Hoffmann degradation are Na₂CO₃, NaBr and H₂O.
Answer: (C)
Solution
RCONH₂+Br₂+4NaOH→RNH₂+Na₂CO₃+2NaBr+2H₂O, so 1 mole of Br₂ is consumed (A false). The reaction works for alkyl (aliphatic) amides (B
