Vedclass · Answer

(B) The reaction between benzaldehyde $(C_6H_5CHO)$ and acetaldehyde $(CH_3CHO)$ in the presence of dilute alkali is a Claisen-Schmidt condensation.Acetaldehyde acts as the nucleophile by forming an enolate ion,which attacks the carbonyl carbon of benzaldehyde.The initial aldol product formed is $C_6H_5-CH(OH)-CH_2-CHO$ ($3$-hydroxy$-3-$phenylpropanal).This product undergoes spontaneous dehydration in the presence of base and heat to form the more stable conjugated product,cinnamaldehyde $(C_6H_5-CH=CH-CHO)$.
