Vedclass · Answer

(B) The given reaction is an example of an intramolecular Cannizzaro reaction. The $OH^-$ ion attacks the more electrophilic aldehyde carbonyl carbon. Subsequently,a hydride ion $(H^-)$ shifts from the aldehyde carbon to the ketone carbonyl carbon. This is followed by a proton transfer to yield the salt of a hydroxy acid,which is sodium mandelate $(Ph-CH(OH)-COONa)$.
