I recently did an experiment on Aldol Condensation, by reacting Benzaldehyde with Acetone to form Dibenzalacetone.
The proposed stoichiometric ratio of Benzaldehyde:Acetone is 2:1.
What would be the implications if either of the reactants is in excess?
Either reactant in excess will drive the equilibrium to the right (Le Chatelier's Principle). Also, look to see if side reactions are possible, and if so, how those might be affected.
What are the possible side reactions for this case?
