Vedclass · Answer

(B) When two different aldehydes,both containing $\alpha$-hydrogen atoms,undergo aldol condensation,a mixture of $4$ products is formed. These include two self-aldol products and two cross-aldol products. $1.$ Self-aldol of $CH_3CHO$: $CH_3-CH(OH)-CH_2-CHO$ $2.$ Self-aldol of $CH_3CH_2CHO$: $CH_3-CH_2-CH(OH)-CH(CH_3)-CHO$ $3.$ Cross-aldol (Ethanal as acceptor + Propanal as enolate): $CH_3-CH(OH)-CH(CH_3)-CHO$ $4.$ Cross-aldol (Propanal as acceptor + Ethanal as enolate): $CH_3-CH_2-CH(OH)-CH_2-CHO$.
