The reaction of an amide with bromine in the presence of potassium hydroxide is known as:

Solution

1. The reaction is ${\text{RCONH}}_2+{\text{Br}}_2+4\text{KOH}\to {\text{RNH}}_2+{\text{K}}_2{\text{CO}}_3+2\text{KBr}+2{\text{H}}_2\text{O}$.
2. This reaction is specifically used to prepare primary amines with one carbon atom less than the starting amide.
3. This transformation is named Hofmann bromamide degradation.
4. Hence the answer is (A).
