Identify the Carbonyl compound which will not be formed when hydration of Alkynes is carried out with dil. \( H_2SO_4/Hg^{2+} \) at 333 K. Acetone, Butanal, Ethanal, Butanone.
Show Hint
Hydration of alkynes in presence of \( Hg^{2+}/H_2SO_4 \) gives ketones via enol-keto tautomerismAldehydes are not formed in this reaction.
