Choose the True product of the following reaction?CH3C≡N+2H2O+HCl→
Correct answer: B. CH3COOH +NH4Cl
- A. CH3COOH +NH3
- B. CH3COOH +NH4Cl
- C. CH3COCl +NH3
- D. CH3CONH2
Explanation
Students should remember that nitriles react with aqueous HCl in a hydrolysis reaction to form the corresponding carboxylic acid and salt of anion so the correct option is B which gives us ethanoic acid and ammonium chloride (salt)

About Nomenclature, Structure and Preparation
Carboxylic acids are prepared by oxidising primary alcohols or aldehydes, hydrolysing nitriles, esters and amides, and carbonating suitable organometallic compounds. Their structures, IUPAC naming, resonance stabilisation and acidic character explain why carboxylic acids differ from alcohols and phenols, despite all containing oxygen and hydrogen.
