In this experiment, benzyl and dibenzyl ketone will produce tetraphenylcyclopentadienone via aldol condensation reaction.
1.) What is a condensation reaction? What is the small molecule lost in this reaction?
2.) In this reaction, all the reactants are ketone compounds. Can condensation reactions be extended to other carbonyl compounds than ketones?
3.) What is an enol? In a tautomerization equilibrium, will the enol or the keto isomer will be favored?
4.) What is the driving force for the enolization? (what causes the enolate ion to be formed?)
5.) The reaction goes through color change. Why the color change happens in this reaction and how can this information is associated with the (predicted) success of this reaction?
6.) Side Products Possibilities:. Assume that and enolized molecule of dibenzyl ketone attacks another dibenzyl ketone. Write the overall chemical reaction.
