Acetophenone (CX6HX5COCHX3) and benzaldehyde are warmed with NaOH in ethanol until dehydration is complete (Claisen-Schmidt condensation). The product is
A1,3-diphenylpropan-1-one
B3-hydroxy-1,3-diphenylpropan-1-one
C1,3-diphenylprop-2-en-1-one
D1,2-diphenylethane-1,2-dione
Answer: C
The enolate of acetophenone attacks benzaldehyde, and the beta-hydroxy ketone loses water. This gives CX6HX5CH=CHCOCX6HX5, chalcone, 1,3-diphenylprop-2-en-1-one.
