a. The yield of the reaction to form your chalcone is not quantitative. What side products might be formed from your aldol condensation?

b. If one uses benzaldehyde rather than p-nitrobenzaldehyde in the aldol reaction the yield is extremely low, if it works at all. Offer an explanation for this result.
