Question Image

The hydration of an alkyne in the presence of dilute sulfuric acid and mercuric sulfate typically leads to the formation of a ketone via an intermediate enol, which rearranges to the more stable ketone.

Propyne (CH₃C≡CH), when hydrated, follows the Markovnikov rule, meaning that the -OH group will attach to the carbon with the most hydrogen atoms (the less substituted carbon of the alkyne), while the -H will add to the more substituted carbon.

This results in the formation of propanone (CH₃COCH₃), a ketone, after the initial formation of an enol intermediate, which tautomerizes to the more stable ketone.
