Vedclass · Answer

(A) The reaction of phenylacetylene with $dil. H_2SO_4$ in the presence of $HgSO_4$ is an acid-catalyzed hydration known as the Kucherov reaction.According to Markovnikov's rule,the $-OH$ group attaches to the carbon atom with fewer hydrogen atoms.The intermediate enol $[Ph - C(OH) = CH_2]$ undergoes tautomerization to form the stable ketone,acetophenone $(Ph - CO - CH_3)$.

What is the final product of the reaction: $Ph - C \equiv CH \xrightarrow[HgSO_4]{dil. H_2SO_4} \text{Product}$?
