Vedclass · Answer

(A) The oxymercuration-demercuration (or hydration) of terminal alkynes like $1$-butyne $(CH_3-CH_2-C \equiv CH)$ in the presence of $HgSO_4$ and $H_2SO_4$ follows Markovnikov's rule. $1$. The addition of water across the triple bond forms an enol intermediate: $CH_3-CH_2-C(OH)=CH_2$. $2$. This enol undergoes tautomerization to form a stable ketone. $3$. The final product is $2$-butanone $(CH_3-CH_2-CO-CH_3)$.

What product is obtained by the oxymercuration of $1$-butyne using $HgSO_4 + H_2SO_4$?
