(A) The reaction of an internal alkyne with $Hg^{2+}/H^{+}$ (Kuccherov reaction) involves the hydration of the alkyne to form a ketone.For the unsymmetrical alkyne $Ph-C \equiv C-CH_3$,the hydration can occur at either carbon of the triple bond.However,the formation of the ketone is governed by the stability of the intermediate carbocation or the electronic effects of the substituents.In this case,the reaction proceeds to form $Ph-CO-CH_2-CH_3$ (propiophenone derivative) as the major product,which corresponds to the structure in image $287-$a474.

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