● Cross aldol condensation-
Aldol condensations between different carbonyl reactants are called cross aldol condensations.

● Cross aldol products of Ethanal + Propanal -
- IUPAC Name - 2-methylbut-2-enal
Structure - CH3-CH=C(CH3)-CHO

- IUPAC Name - Pent-2-enal
Structure - CH3-CH2-CH=CH-CHO

- IUPAC Name - But-2-enal
Structure - CH3-CH=CH-CHO

- IUPAC Name - 2-methylpent-2-enal
