Acid-hydrolysis of benzonitrile forms

Options

  1. Abenzylamine
  2. Baniline
  3. Cbenzoic acid
  4. Dphenol

Correct answer

C. benzoic acid

Step-by-step solution

Acid-hydrolysis of benzonitrile forms benzoic acid. C 6 H 5 C N → H 3 O + C 6 H 5 C O N H 2 → H 3 O + C 6 H 5 C O O H + N H 4 + Note: Alkaline-hydrolysis of cyanide forms benzoate and N H 3 . C 6 H 5 C N → H 2 O / O H - C 6 H 5 C O N H 2 → H 2 O / O H - C 6 H 5 C O O - + N H 3
