Question

Which of the following reaction is appropriate for converting acetamide to methanamine?

• A. Gabriel phthalimide synthesis
• B. Stephens reaction
• C. Hoffmann hypobromamide reaction
• D. Carbylamine reaction

Answer 1

The correct option is C Hoffmann hypobromamide reaction

In Hoffmann hypobromamide reaction, an amide is converted to primary amine on reacting with $B{r}_2/NaOH$.
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.
