Vedclass · Answer

(D) The Cannizzaro reaction is characteristic of aldehydes that do not possess an $\alpha$-hydrogen atom.$A$. $Ph-CHO$ (Benzaldehyde) has no $\alpha$-hydrogen,so it undergoes the Cannizzaro reaction.$B$. Furfural has no $\alpha$-hydrogen,so it undergoes the Cannizzaro reaction.$C$. $Me_2CH-CHO$ (Isobutyraldehyde) has one $\alpha$-hydrogen,but it is a known exception that can undergo the Cannizzaro reaction under specific conditions.$D$. $Ph-CH_2-CHO$ (Phenylacetaldehyde) has two $\alpha$-hydrogens. Aldehydes with $\alpha$-hydrogens typically undergo aldol condensation rather than the Cannizzaro reaction in the presence of aqueous alkali. Therefore,it will not undergo the Cannizzaro reaction.

Which of the following compounds will not undergo the Cannizzaro reaction when treated with $50\%$ aqueous alkali?
