NEET levelSingle correct optionDifficulty 1 of 3o1168

Acetic anhydride reacts with ethanol. The products are

  1. Aethyl acetate and acetic acid
  2. Bacetaldehyde and ethyl acetate
  3. Cdiethyl ether and acetic acid
  4. Dethyl acetate and water

Answer: A

Ethanol attacks one acyl carbon; the carboxylate (, protonated to acetic acid) is the leaving group. One acyl group is transferred to the alcohol, giving the ester and one mole of acetic acid.
