Question

When two different carbonyl compounds containing $\alpha$-hydrogens react in the presence of dilute NaOH and heat, the reaction is known as

• A. Aldol condensation
• B. Self condensation
• C. Cross aldol condensation
• D. None of the above

Answer 1

The correct option is C Cross aldol condensation

Aldol condensation occurs in aldehydes having α-hydrogen with a dilute base to give β-hydroxy aldehydes called aldols. This reaction is most commonly known as aldol condensation. If the condensation reaction occurs between two different carbonyl compounds it is called crossed aldol condensation.

Hence, the correct answer is option (c).
