Vedclass · Answer

(B) The hydration of ethyne $(HC \equiv CH)$ in the presence of $HgSO_4$ and dilute $H_2SO_4$ at $333 \ K$ proceeds via the formation of an unstable enol intermediate,vinyl alcohol $(CH_2=CH-OH)$.This intermediate undergoes tautomerization to form the stable carbonyl compound,ethanal $(CH_3CHO)$.

The final product obtained by heating ethyne in the presence of $HgSO_4$ and dilute $H_2SO_4$ at $333 \ K$ is .........
