(B) The hydration of alkynes in the presence of $Hg^{2+}$ salts (like $HgSO_4$) and dilute acid (like $H_2SO_4$) follows Markovnikov's rule.For propyne $(CH_3-C \equiv CH)$,the addition of water occurs across the triple bond.The initial product is an enol $(CH_3-C(OH)=CH_2)$,which is unstable and undergoes tautomerization to form a stable ketone.Specifically,propyne yields acetone $(CH_3-CO-CH_3)$.
