Solution
The correct option is C Hoffmann hypobromamide reaction In Hoffmann hypobromamide reaction, an amide is converted to primary amine on reacting with Br2/NaOH.
The primary amine thus formed contains one carbon less than the number of carbon atoms in that amide
Thus, acetamide gives methanamine in Hoffmann hypobromamide reaction.
Hence, option (b) is correct.
