JEE Main levelSingle correct optionDifficulty 2 of 3o1073

Ethyl 3-oxobutanoate is treated with in ethanol at , followed by dilute acid work-up. The main product is

  1. Aethyl butanoate
  2. B3-oxobutan-1-ol
  3. Cethyl 3-hydroxybutanoate
  4. Dbutane-1,3-diol

Answer: C

is a mild reagent that reduces aldehydes and ketones but does not reduce esters under these conditions. Only the ketone group is reduced to , giving ethyl 3-hydroxybutanoate.
