Vedclass · Answer

(C) The reaction involves the nucleophilic attack of the cyanide ion $(CN^{-})$ on the carbonyl carbon. To generate $CN^{-}$ from $HCN$,a base is required to abstract the proton from $HCN$. The base used must be stronger than the cyanide ion $(CN^{-})$ to effectively shift the equilibrium towards the formation of $CN^{-}$. Among the given options,the ethoxide ion $(EtO^{-})$ is a stronger base than the cyanide ion $(CN^{-})$,making it an effective catalyst for this reaction.

The reaction $R-C(=O)-R + HCN \xrightarrow{\text{catalyst}} R-C(OH)(CN)-R$ is a nucleophilic addition reaction. Which of the following can be used as a catalyst in the above reaction?
