JEE Advanced levelOne or more correct optionsDifficulty 3 of 3ro127

Excess in dry ether, followed by work-up, is used. Which conversions are correct?

  1. AButanenitrile to butan-1-amine
  2. BN,N-Dimethylbenzamide to N,N-dimethylbenzylamine
  3. COct-1-ene to octane
  4. DBenzoic acid to benzyl alcohol

Answer: A, B, D

reduces nitriles to primary amines, tertiary amides to amines (the C=O oxygen is removed) and carboxylic acids to primary alcohols, so (A), (B) and (D) are correct. An isolated such as in oct-1-ene is not attacked, so (C) is wrong.
