Vedclass · Answer

(C) The reaction of an alkyne with $H^{+}/Hg^{2+}$ (mercuric sulfate in dilute sulfuric acid) is a hydration reaction that follows Markovnikov's rule.$Ph-C \equiv C-CH_3 + H_2O \xrightarrow{H^{+}/Hg^{2+}} Ph-C(OH)=CH-CH_3$ (enol intermediate).The enol intermediate undergoes tautomerization to form the more stable ketone.$Ph-C(OH)=CH-CH_3 \rightleftharpoons Ph-CO-CH_2CH_3$ (propiophenone).Thus,the final product $A$ is $Ph-CO-CH_2CH_3$.

$Ph-C \equiv C-CH_3 \xrightarrow{H^{+}/Hg^{2+}} A$
the product $A$ is
