Find the major organic product obtained from the following hydration reaction
a)The major organic product obtained from the following hydration reaction – option a
b) The major organic product obtained from the following hydration reaction – option b
c) The major organic product obtained from the following hydration reaction – option c
d) The major organic product obtained from the following hydration reaction – option d
Answer: b
Explanation: Treatment of an alkyne with aqueous acid in the presence of Hg2+ results in a hydration reaction to form an enol, which tautomerizes to form a ketone. The regiochemistry of the addition is that predicted by Markovnikov’s rule, with the oxygen adding to the more substituted end of the carbon-carbon triple bond.
