(318)

The condensation of an aromatic aldehyde (without $α$ hydrogen) with an aliphatic aldehyde or ketone (having $α$ hydrogen) in the presence of a strong base (hydroxide or alkoxide) to give $α$ , $β$ unsaturated aldehydes or ketones is called Claisen-Schmidt condensation reaction.

$Moles of dibenzalacetone = \frac{Mass of dibenzalacetone}{molar mass}$

$= \frac{351}{234} mol = 1.5 mol$

By stoichiometry of reaction, moles of benzaldehyde = 2 $\times$ moles of dibenzalacetone = 2 $\times$ 1.5 = 3mol.

Mass of benzaldehyde = moles of benzaldehyde $\times$ molar mass of benzaldehyde = 3mol $\times$ 106 ${gmol}^{- 1}$ = 318 g
