Case ii) Aldol condensation in two molecules of propanal, in which one acts as nucleophile and other as an electrophile. Case iii) Aldol condensation in between of one molecule of propanal and butanal in which propanal acts as a nucleophile and butanal acts as an electrophile. Step 1 through 3 are a crossed aldol reaction, steps 4 and 5 a 1,2-elimination via E1cB mechanism. Thus, crossed aldol condensation is crossed aldol reaction followed by 1,2-elimination. Thus, crossed aldol condensation is crossed aldol reaction followed by 1,2-elimination.
