Aqueous 10 % NaHCO ₃ solution is used as a reagent for identifying ' A '. Which of the following compounds yield ' A ' on hydrolysis?

Options

  1. ACH ₃ COOC ₂ H ₅
  2. BC ₂ H ₅- COO - C ₂ H ₅
  3. CCH ₃ CHO
  4. DCH ₃ CH ₂ OH

Correct answer

A. CH ₃ COOC ₂ H ₅

Step-by-step solution

NaHCO ₃ is basic in nature so it is used in the identification of acid only. In the given compound only ester ( CH ₃ COOC ₂ H ₅ ) on hydrolysis gives acid as Ethyl acetate CH ₃ COOC ₂ H ₅ + H ₂ O Acetic acid CH ₃ COOH + C ₂ H ₅ OH (Ethyl alcohol)
