CH3CN +H2O + HCl → A + B In the reaction given above, A and B are:
Correct answer: D. Acetic acid and ammonium chloride
- A. Acetic acid and acid amide
- B. Acetic acid and methyl chloride
- C. Acetic acid and ammonia
- D. Acetic acid and ammonium chloride
Explanation
The acid-catalyzed hydrolysis of a nitrile (CH3CN) first produces an amide, which is then further hydrolyzed to a carboxylic acid (acetic acid. A). The nitrogen from the nitrile combines with the acid (HCI) and water to form an ammonium salt (ammonium chloride, B).

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
