Identify the product ' B ' in the following sequence of reactions. Methylpropanoate dil. NaOH A [ Conc. HCl ] H ⁺ B

Options

  1. Asodium propanoate
  2. Bpropanone
  3. Cpropanal
  4. Dpropanoic acid

Correct answer

D. propanoic acid

Step-by-step solution

Hydrolysis of methylpropanoate with dilute sodium hydroxide yields sodium propanoate via saponification: CH₃ CH₂ COOCH₃ + NaOH CH₃ CH₂ COONa + CH₃ OH Subsequent acidification with concentrated hydrochloric acid converts the salt to propanoic acid: CH₃ CH₂ COONa + H+ CH₃ CH₂ COOH + Na+ Thus product B is propanoic acid, corresponding to option D.
