Question
Explain Cross aldol condensation with suitable example. ### Write a short note: Cross aldol condensation.
✓
Answer
→ Cross aldol condensation : "When aldol condensation is carried out between two diferite and/or ketones, it is called cross aldol condensation." If both of them contain $\alpha$-hydrogen atoms, it gives a mixture of four products. This is illustrated below by aldol reaction of a mixture of ethanal and propanal.
→ Ketones can also be used as one component in the cross aldol reactions.
→ Ketones can also be used as one component in the cross aldol reactions.
