Vedclass · Answer

(D) The reaction described is the Wacker process,where ethylene $(CH_2=CH_2)$ is oxidized to acetaldehyde $(CH_3CHO)$ in the presence of $PdCl_2$ and $CuCl_2$. Thus,$X$ is acetaldehyde $(CH_3CHO)$. Acetaldehyde contains a carbonyl group $(C=O)$ and undergoes nucleophilic addition reactions. Among the given options,$HCN$ (hydrogen cyanide) is a classic reagent that readily undergoes nucleophilic addition with the carbonyl group of aldehydes to form cyanohydrins. Therefore,$HCN$ is the correct reagent.

Column-$I$ (Compound)	Column-$II$ (Attraction Forces)
$A$. Aldehyde	$i$. Intermolecular hydrogen bond formed in $ROH$ between $O^{\delta -}$ of one molecule and $H^{\delta +}$ of another molecule.
$B$. Ketone	$ii$. Dipole-dipole forces between $C^{\delta +}$ of one molecule and $O^{\delta -}$ of another molecule.
$C$. Alcohol	$iii$. van der Waals forces
$D$. Alkane	$iv$. Ionic forces
