The product Q and R in the following reactions respectively are H 2 + CH 3 C ≡ CH →   Lindlar ' s   catalyst P → Zn + H 2 O O 3 Q + R

Options

  1. AEthanol. Methanoic Acid
  2. BEthanoic acid, Methanol
  3. CEthanal, Methanal
  4. DEthanoic acid, Methanoic acid

Correct answer

C. Ethanal, Methanal

Step-by-step solution

Lindlar's Catalyst transforms an alkyne to a alkene because the hydrogenation reaction is occurring on the surface of the poisned metal. The alkene reacts with ozone in the presence of Zn / H 2 O gives carbonyl compounds.
