Which of the following is NOT prepared by the action of Grignard's reagent on methanal?
  1. Ethanol
  2. Propan-1-ol
  3. Propan-2-ol
  4. Butan-1-ol

Solution

Methanal (formaldehyde) on reaction with Grignard reagent gives primary alcohols. Hence, propan-2-ol (secondary alcohol) cannot be prepared by the action of Grignard reagent on methanal.
