(A) The hydration of propyne $(CH_3-C\equiv CH)$ in the presence of $H_2SO_4$ and $HgSO_4$ follows Markovnikov's addition.First,an unstable enol intermediate,$CH_3-C(OH)=CH_2$ (prop-$1$-en-$2$-ol),is formed.This enol undergoes tautomerization to form the stable ketone,$CH_3-CO-CH_3$ (propan-$2$-one or acetone).Reaction: $CH_3-C\equiv CH + H_2O$ $\xrightarrow[HgSO_4]{H_2SO_4} [CH_3-C(OH)=CH_2]$ $\rightarrow CH_3-CO-CH_3$.

The hydration of propyne results in the formation of:
