Vedclass · Answer

(C) The hydration of alkynes in the presence of $HgSO_4$ and $H_2SO_4$ follows Markovnikov's rule.$1$. $HC \equiv CH + H_2O \xrightarrow{HgSO_4, H_2SO_4} CH_2=CH(OH) ightleftharpoons CH_3-CHO$ (Ethanal).$2$. Cyclohexylacetylene + $H_2O \xrightarrow{HgSO_4, H_2SO_4} 	ext{Cyclohexyl methyl ketone}$.$3$. $CH_3-C \equiv CH + H_2O \xrightarrow{HgSO_4, H_2SO_4} CH_3-C(OH)=CH_2 ightleftharpoons CH_3-CO-CH_3$ (Propanone).$4$. $CH_3-C \equiv C-CH_3 + H_2O \xrightarrow{HgSO_4, H_2SO_4} CH_3-C(OH)=CH-CH_3 ightleftharpoons CH_3-CO-CH_2-CH_3$ (Butan$-2-$one).$CH_3-CH_2-CHO$ (Propanal) is an aldehyde that cannot be formed by the hydration of any alkyne because the hydration of terminal alkynes (other than ethyne) always yields a ketone due to the formation of a more stable secondary enol intermediate.

Which one of the following carbonyl compounds cannot be prepared by addition of water on an alkyne in the presence of $HgSO_4$ and $H_2SO_4$?
