Cross-aldol condensation between acetaldehyde and acetone gives:
Solution
Cross-aldol: acetaldehyde can act as electrophile or nucleophile; acetone can also. Possible products: aldol from acetaldehyde self-condensation, aldol from acetone self, and 2 cross products = 4? Actually self-condensation of acetaldehyde → product 1; self-condensation of acetone → product 2; cross → product 3 and 4. But acetone is less reactive so only 3 major products.
