Solution
Correct Answer:
Methylamine
This conversion is the Hofmann bromamide reaction, where an amide gives a primary amine with one carbon less than the parent amide. Acetamide has two carbons, so after rearrangement and decarbonylation, the product amine contains one carbon: methylamine. Ethylamine would require retention of both carbons, which does not happen in this reaction. Thus the correct product is methylamine.
This medium difficulty chemistry question is from the chapter organic compounds containing nitrogen, covering the topic of preparation of amines. It appeared in the 2025 exam.
