- 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 CelsiusWhich statement describes why aldol reactions with ketones are low yielding? A.Ketones do not have acidic protons. B.Ketones are too electron poor at the carbonyl carbon. C.Ketones can attack other ketones well but perform poorly in self-condensations. D.The product of a ketone addition to a ketone has considerable steric strain.In 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.
- I need a pushing mechanism for 3,4 dimethoxy-benzaldehyde and 1-indanone in the presence of NaOH. This is a aldol reaction.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 annulationYour 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.
