NEET2010ChemistryAminesActual
Acetamide is treated with the following reagents separately. Which one of these would yield methyl amine ?
Options
- ANaOH - Br ₂
- BSodalime
- CHot conc H ₂ SO ₄
- DPCl ₅
Correct answer
A. NaOH - Br ₂
Step-by-step solution
Key Idea The reagent which can convert - CONH ₂ group into - NH ₂ group is used for this reaction. Among the given reagents only NaOH / Br ₂ converts - CONH ₂ group to - NH ₂ group, thus it is used for converting acetamide to methyl amine. This reaction is called Hofmann bromamide reaction. aligned & acetamide CH ₃ CONH ₂ + NaOH + Br ₂ array c CH ₃ NH ₂ methyl amine array &+ NaBr + Na ₂ CO ₃+ H ₂ O aligned
