Solution
The correct option is A
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.
Acid-catalyzed hydration of internal alkynes can produce one or two ketones depending if the alkyne is symmetrical or not. And terminal alkynes produce only one ketone following the Markovnikov’s rule. Hence the correct option is (a).
