- What is the starting material for this product of a intramolecular aldol condensation reaction?for the theroretical yield is the mol correct? also using the aldol condensation reaction in this portion are we using the aldol condensation reaction to synthesize acetophenone and para-methybenzaldehye. acetophenone 0.5 g, 4.2 mmol Para-methylbenzaldehyde 0.5 g, 4.2 mmol NaOH=0.18g = 4.5 mol Theroretical yield=0.93g =0.0519 mol Percent yield=76.8% Actual yield= 0.715 g Melting point observered= 93 degree Celsius Expected melting point =93-94.5 degree CelsiusIn a mixed aldol condensation with unknown aldehydes and ketones experiment, some aldol condensation reactions need to be heated for the dehydration step to occur. Explain why that was not necessary for the reactions carried out in this experiment? [Hint: what makes the product especially stable?]. This experiment used ethanol, acetic acid, sodium hydroxide, cyclohexanone and 4- methoxybenzaldehyde.
- Draw the major organic product that forms in an intramolecular aldol condensation. Remember that heat is applied.Please complete the Aldol condensation reactions shown belowYour aldol condensation procedure calls for refluxing vanillin in acetone and NaOH for an hour. Whatmight happen if you didn’t heat the reaction, or heated it for too short a time? a) A mixture of aldol products and hydroxyketone intermediates would form.b) No reaction would occur, as the heat is needed to deprotonate the acetone.c) The reaction would still be successful.d) No reaction would occur, as the heat is needed to dissolve the NaOH.
- i need the mechanism for aldol condensation involving benzaldehyde and acetoneDraw the arrow pushing mechanism for the Aldol condensation converting vanillin to dehydrozingerone. ( be specific use vanillin and acetone and show its conversion to dehydrozingerone not just some general aldol condensation.)All are true or false a) The initially formed b-hydroxy carbonyl compound loses water in a Aldol condensation. b) Equilibrium favors the starting materials with both aldehydes and ketones for Aldol reactions. c)The Claisen reaction is a type of nucleophilic addition? d) The b-hydroxy carbonyl product of an Aldol reaction is oftentimes not the final isolated product. e)b-Ketoester and an enolate are the two starting materials for a Robinson annulation
