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.
