Question 41

Alkanoic Acids and Esters

CH3COOH + CH3CH2OH → X + Y (conc. H2SO4)
X and Y in the reaction above are respectively

  1. A.CH3COCH3 and H2O
  2. B.CH3CH2COCH3 and H2O
  3. C.CH3COOCH2CH3 and H2O
  4. D.CH3CH2CHO and CH4
Show the answer and explanation

Answer: C (CH3COOCH2CH3 and H2O)

Explanation

An acid and an alcohol react (esterification) to form an ester and water. Ethanoic acid and ethanol give ethyl ethanoate, CH3COOCH2CH3, and H2O.
