Vedclass · Answer

(D) Aldol condensation occurs in aldehydes and ketones that possess at least one $\alpha$-hydrogen atom.$1$. Propanal $(CH_3CH_2CHO)$ has $2$ $\alpha$-hydrogen atoms.$2$. Trichloroethanal $(Cl_3CCHO)$ has no $\alpha$-hydrogen atoms.$3$. Methanal $(HCHO)$ has no $\alpha$-hydrogen atoms.$4$. Ethanal $(CH_3CHO)$ has $3$ $\alpha$-hydrogen atoms.$5$. Benzaldehyde $(C_6H_5CHO)$ has no $\alpha$-hydrogen atoms.Therefore,trichloroethanal $(2)$,methanal $(3)$,and benzaldehyde $(5)$ do not undergo aldol condensation.
