Vedclass · Answer

(A) The reaction between two different carbonyl compounds (benzaldehyde and acetophenone),where at least one of them has an $\alpha$-hydrogen atom (acetophenone has three $\alpha$-hydrogens),in the presence of a dilute base like $NaOH$ is called $Cross$ $Aldol$ $condensation$. Benzaldehyde $(C_6H_5CHO)$ does not have an $\alpha$-hydrogen,while acetophenone $(C_6H_5COCH_3)$ has $\alpha$-hydrogens. This specific reaction leads to the formation of a $\beta$-hydroxy ketone,which upon dehydration gives an $\alpha,\beta$-unsaturated ketone.

The reaction between benzaldehyde and acetophenone in the presence of dilute $NaOH$ is known as:
