The end product in the following sequence of reaction is
A.Acetic acid
B.Isopropyl alcohol
C.Acetone✓ Correct
D.Ethanol
Explanation
The reactant in the given reaction is ethyne, so when ethyne is reacted with HgSO4 there will be formation of ethanal. Now when this ethanal is reacted withCH3MgX , then there is formation of a secondary alcohol, propan- 2-ol. We know that secondary alcohol on oxidation forms ketone, so propan-2-ol on oxidation will form acetone. The reaction is given below:
