Reaction:
Propyne can undergo acid-catalyzed hydration in the presence of aqueous H2SO4 and HgSO4.
Major Product:
The major product obtained in this reaction is Acetone (CH3COCH3).
Explanation:
- Propyne undergoes hydration in the presence of aqueous H2SO4 and HgSO4 to form acetone.
- The reaction proceeds via the addition of water across the triple bond of propyne, followed by tautomerization to form the ketone acetone.
- The presence of HgSO4 helps in the formation of a mercurinium ion intermediate, which facilitates the addition of water to the triple bond.
- The final product obtained is acetone, which is a ketone with the molecular formula CH3COCH3.
