Vedclass · Answer

(C) The reaction of $CH_3CHO$ with $4HCHO$ in the presence of $conc. aq. NaOH$ proceeds through a series of steps. $1$. The first step is an aldol condensation between $CH_3CHO$ and $HCHO$ to form $HOCH_2-CH_2-CHO$. $2$. The second step is another aldol condensation with $HCHO$ to form $(HOCH_2)_2CH-CHO$. $3$. The third step is a final aldol condensation with $HCHO$ to form $(HOCH_2)_3C-CHO$. $4$. The final step is a Cannizzaro reaction where the aldehyde group is reduced to an alcohol group,resulting in pentaerythritol $(HOCH_2)_4C$. Thus,there are $3$ aldol reactions involved in the transformation.

The number of aldol reaction$(s)$ that occurs in the given transformation is :
