$C_6H_5-CO-CH_3$

Vedclass · Answer

(A) The reaction of phenylacetylene $(C_6H_5-C \equiv CH)$ with dilute $HgSO_4$ in the presence of $H_2SO_4$ is an example of oxymercuration-demercuration hydration of an alkyne. This reaction follows Markovnikov's rule,where the water molecule adds across the triple bond. The initial product is an enol,$C_6H_5-C(OH)=CH_2$. This enol is unstable and undergoes tautomerization to form a more stable ketone,acetophenone $(C_6H_5-CO-CH_3)$.

What is formed when phenylacetylene reacts with dilute $HgSO_4$ in the presence of $H_2SO_4$?
