(A) The hydration of $1$-butyne $(CH_3-CH_2-C \equiv CH)$ in the presence of $HgSO_4$ and $H_2SO_4$ follows Markovnikov's rule.Water adds across the triple bond to form an unstable enol intermediate $(CH_3-CH_2-C(OH)=CH_2)$.This enol then tautomerizes to form the more stable ketone,$2$-butanone $(CH_3-CH_2-C(=O)-CH_3)$.
