Vedclass · Answer

(A) The reaction is a mixed aldol condensation between propanal $(CH_3CH_2CHO)$ and benzaldehyde $(C_6H_5CHO)$.Propanal has $\alpha$-hydrogens,while benzaldehyde does not.Possible products are:$1$. Self-aldol of propanal: $CH_3CH_2CH(OH)CH(CH_3)CHO$.$2$. Cross-aldol (propanal as nucleophile,benzaldehyde as electrophile): $C_6H_5CH(OH)CH(CH_3)CHO$.Since benzaldehyde cannot form an enolate,it cannot act as a nucleophile,so no other cross-aldol or self-aldol products are formed.Thus,there are $2$ aldol products obtained.
