JEE Main levelSingle correct optionDifficulty 2 of 3co147

But-2-enal, , is treated with aluminium isopropoxide in excess propan-2-ol (Meerwein-Ponndorf-Verley reduction) and then hydrolysed. The product is

  1. Abutan-1-ol
  2. Bbutanal
  3. Cbut-2-en-1-ol
  4. Dbutan-2-ol

Answer: C

MPV reduction transfers hydride from the isopropoxide to the carbonyl carbon only; the C=C is untouched. The product is the allylic alcohol , but-2-en-1-ol.
