Which of the following transformations by in methanol at room temperature are correctly described?

  1. ACyclohexanone is reduced to cyclohexanol.
  2. BEthyl benzoate is reduced to benzyl alcohol.
  3. C4-Acetylbenzonitrile is reduced to 4-(1-hydroxyethyl)benzonitrile, the nitrile being unaffected.
  4. DBenzoic acid is reduced to benzyl alcohol.

Answer: A, C

in methanol reduces aldehydes and ketones, so options (A) and (C) are correct, and the nitrile in (C) survives. Esters and carboxylic acids are not reduced under these mild conditions, so (B) and (D) are wrong; these need .
