Vedclass · Answer

(D) The reaction of $C_2H_2$ (acetylene) with $H_2O / H_2SO_4, Hg^{2+}$ at $333 \ K$ is the hydration of an alkyne,which yields acetaldehyde $(CH_3CHO)$. Thus,$x = H_2O / H_2SO_4, Hg^{2+}$.The conversion of $CH_3-CH=CH-CH_2OH$ (crotyl alcohol) to $CH_3-CH=CH-CHO$ (crotonaldehyde) involves the oxidation of a primary allylic alcohol to an aldehyde. $PCC$ (Pyridinium chlorochromate) is a selective oxidizing agent that oxidizes primary alcohols to aldehydes without further oxidation to carboxylic acids. Thus,$y = PCC$.
