Vedclass · Answer

(A) The reaction between benzaldehyde $(C_6H_5CHO)$ and acetophenone $(CH_3COC_6H_5)$ in the presence of dilute $NaOH$ is a Claisen-Schmidt condensation reaction. Benzaldehyde acts as the electrophile,and acetophenone acts as the nucleophile (enolate donor). The reaction proceeds as follows: $C_6H_5CHO + CH_3COC_6H_5 \xrightarrow{NaOH} C_6H_5CH=CHCOC_6H_5 + H_2O$. The final product is benzylidene acetophenone (also known as chalcone).
