Vedclass · Answer

(A) The cross aldol condensation of ethanal $(CH_3CHO)$ and propanal $(CH_3CH_2CHO)$ involves four possible products:$1$. Self-aldol of ethanal: $CH_3CH=CHCHO$ (But$-2-$enal)$2$. Self-aldol of propanal: $CH_3CH_2CH=C(CH_3)CHO$ ($2-$Methylpent$-2-$enal)$3$. Cross-aldol (ethanal as nucleophile): $CH_3CH_2CH=CHCHO$ (Pent$-2-$enal)$4$. Cross-aldol (propanal as nucleophile): $CH_3CH=C(CH_3)CHO$ ($2-$Methylbut$-2-$enal)Comparing these with the options,$3-$Methylbut$-2-$enal is not formed.

Which of the following is not a final product obtained by cross aldol condensation of ethanal and propanal?
