Carboxylic acid can be prepared by hydrolysis of Nitrile in acidic condition.If acetonitrile undergoes hydrolysis, what is the product?
Correct answer: B. Acetic acid
- A. Formic acid
- B. Acetic acid
- C. Propionic acid
- D. Nitric acid
Explanation
Carboxylic acid can be prepared from Acetonitrile via hydrolysis to from a carboxylic acid and ammonia. Nitrile group contains two pi bonds and is hydrolyzed by hydronium ion (acidic property) until it forms acetamide bond. This bond is protonated with water until it forms an acetic acid and ammonia. In this reaction Acetamide act as an intermediate while Ammonia is a byproduct. Remember: All carbon attached to Nitrile becomes part of Carboxylic Acid.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
