The product Q and R in the following reactions respectively are H2+CH3C≡CH→ Lindlar's catalystP→Zn+H2OO3Q+R
  1. Ethanol. Methanoic Acid
  2. Ethanoic acid, Methanol
  3. Ethanal, Methanal
  4. Ethanoic acid, Methanoic acid

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/H2O gives carbonyl compounds.
