Write structural formulae and names of the four possible aldol condensation products from propanal and butanal. In each case, indicate which aldehyde served as nucleophile and which as electrophile.

Solution

Case i) Aldol condensation in two molecules of butanal, in which one acts as a nucleophile and the other as an electrophile.

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.

Case iv) Aldol condensation in between of one molecule of butanal and propanal in which propanal acts as electrophile and butanal acts as a nucleophile.
