$D-COO^-$ and $CD_3OH$

Vedclass · Answer

(A) The reaction is a Cannizzaro reaction involving formaldehyde-$d_2$ $(CD_2=O)$.In the presence of a strong base $(OH^-)$,aldehydes without $\alpha$-hydrogens undergo disproportionation.One molecule of $CD_2=O$ is oxidized to the formate ion $(D-COO^-)$ and the other is reduced to the corresponding alcohol $(CD_3OH)$.Thus,$X = D-COO^-$ and $Y = CD_3OH$.

$2CD_2=O + OH^- \xrightarrow{\quad} X + Y$ ($Y$ is an alcohol and $D$ is deuterium). Identify $X$ and $Y$.
