Vedclass · Answer

(C) Aldol condensation requires the presence of at least one $\alpha$-hydrogen atom in the aldehyde or ketone molecule.$1$. Benzaldehyde $(C_6H_5CHO)$ has no $\alpha$-hydrogen.$2$. $2, 2-$dimethylpropionaldehyde $((CH_3)_3CCHO)$ has no $\alpha$-hydrogen.$3$. Acetaldehyde $(CH_3CHO)$ has three $\alpha$-hydrogen atoms.$4$. Formaldehyde $(HCHO)$ has no $\alpha$-hydrogen.Therefore,only acetaldehyde can undergo base-catalyzed aldol condensation.
