Which of the following statements is true?
Options
- AAcetamide behaves as both a weak acid and a weak base.
- BAll of the above statements are true.
- CCH ₃ CONH ₂ LiAlH ₄ CH ₃ CH ₂ NH ₂
- DAt room temperature, formyl chloride is unstable and is present in the form of CO and HCl .
Correct answer
B. All of the above statements are true.
Step-by-step solution
Acetamide ( CH ₃ CONH ₂ ) is amphoteric in nature. It acts as a weak base because the lone pair of electrons on the nitrogen atom is delocalized over the carbonyl group, and it acts as a weak acid because the hydrogen atom attached to the nitrogen can be removed by a strong base. Reduction of acetamide with LiAlH ₄ yields ethylamine ( CH ₃ CH ₂ NH ₂ ). Formyl chloride ( HCOCl ) is highly unstable at room temperature and readily decomposes into carbon monoxide ( CO ) and hydrogen chloride ( HCl ). Since all the give
