Cannizzaro reaction

Vedclass · Answer

(C) $(C)$. The given reaction is an intramolecular Cannizzaro reaction. In this reaction,the glyoxal molecule $(OCH-CHO)$ undergoes disproportionation in the presence of a base $(OH^-)$,where one aldehyde group is reduced to an alcohol group $(-CH_2OH)$ and the other is oxidized to a carboxylate group $(-COO^-)$. The overall reaction is: $OCH-CHO + OH^- \xrightarrow{} HOCH_2-COO^-$.
