Step 1: Understanding acetamide.
Acetamide is an amide with both acidic and basic properties. It can act as a weak acid due to the presence of the carbonyl group, and as a base due to the nitrogen atom in the amide group.
Step 2: Analysis of options. (A) Acidic: Acetamide is not strongly acidic. (B) Alkaline: Acetamide is not strongly alkaline. (C) Amphoteric: This is correct because acetamide has both acidic and basic properties. (D) Neutral: Acetamide is not neutral; it exhibits amphoteric behavior. Step 3: Conclusion.
The correct answer is (C) because acetamide is amphoteric, showing both acidic and basic characteristics.
