Vedclass · Answer

(B) The hydration of alkynes in the presence of $HgSO_4$ and $H_2SO_4$ follows Markovnikov's rule. For a symmetrical alkyne like $CH_3-C \equiv C-CH_3$ ($2-$butyne),the addition of water results in the formation of an enol intermediate,which tautomerizes to a ketone. $CH_3-C \equiv C-CH_3 + H_2O \xrightarrow{HgSO_4/H_2SO_4} CH_3-C(OH)=CH-CH_3 \rightleftharpoons CH_3-CO-CH_2-CH_3$. The final product is $2-$butanone.
