Vedclass · Answer

(B) The given reaction is an intramolecular Cannizzaro reaction of phenylglyoxal $(Ph-CO-CHO)$.In the presence of a base like $KOH$,the hydroxide ion attacks the more electrophilic carbonyl carbon (the aldehyde group).This leads to a hydride shift from the aldehyde carbon to the ketone carbonyl carbon.The aldehyde group is oxidized to a carboxylate group $(COO^-)$,and the ketone group is reduced to a secondary alcohol group $(CH(OH))$.Thus,the product formed is $Ph-CH(OH)-COO^-K^+$.

The major product $(P)$ in the following reaction is $:$
