Vedclass · Answer

(B) $Benzaldehyde$ $(C_6H_5CHO)$ reacts with acetone $(CH_3COCH_3)$ in the presence of $NaOH$ to undergo the $Claisen-Schmidt$ condensation reaction.This is a type of cross-aldol condensation.The reaction initially forms an aldol intermediate $(4-phenyl-4-hydroxybutan-2-one)$,which upon heating undergoes dehydration to produce benzalacetone $(C_6H_5-CH=CH-COCH_3)$.The reaction is:$C_6H_5CHO + CH_3COCH_3 \xrightarrow{NaOH, \Delta} C_6H_5-CH=CH-COCH_3 + H_2O$

Benzaldehyde on heating with acetone in the presence of $NaOH$ gives:
