Vedclass · Answer

(C) The reaction of acetaldehyde $(CH_3CHO)$ with excess formaldehyde $(HCHO)$ in the presence of a base like $KOH$ proceeds via a series of aldol additions followed by a crossed Cannizzaro reaction.$1$. $CH_3CHO + 3HCHO \xrightarrow{OH^-} (HOCH_2)_3C-CHO$$2$. $(HOCH_2)_3C-CHO + HCHO + OH^- \rightarrow (HOCH_2)_3C-CH_2OH + HCOO^-$The final product is pentaerythritol,$C(CH_2OH)_4$.

Acetaldehyde can be converted into $C(CH_2OH)_4$ (pentaerythritol) by which reagent?
