Vedclass · Answer

(C) Aldehydes lacking $\alpha-H$ atoms undergo the Cannizzaro reaction when treated with concentrated alkali $(NaOH)$. In this reaction,one part of the molecule is reduced to an alcohol,and the other part is oxidized to a salt of a carboxylic acid. Glyoxal $(CHO-CHO)$ lacks $\alpha-H$ atoms and undergoes an intramolecular Cannizzaro reaction. Upon treatment with $NaOH$ followed by acidification with $H^+$,one aldehyde group is reduced to a $-CH_2OH$ group,and the other is oxidized to a $-CO_2H$ group,resulting in glycolic acid $(CH_2OH-CO_2H)$.

In the following reaction,the product $E$ is
