In our Aldol condensation reaction, p-anisaldehyde and acetophenone were reacted in the presence of NaOH to form trans-p-anisalacetophenone. Provide a benchtop test that can enable a student to confirm that the correct product was obtained at the end of an aldol condensation experiment, and explain how the test will work.

Please Calculate the theoretical yield and the percent yield of this aldol reaction. Unknown ketone: cyclohexanone Unknown aldehyde: p-Anisaldehyde Actual yield: 0.067 Our aldol mixture was our unknown ketone (0.002 mol) with 4.0 mL of 95% ethanol in a 25 mL Erlenmeyer flask. And we added our unknown aldehyde (0.008 mol) and 3.0 mL of 1 M NaOH.

We performed an aldol condensation reaction using
4-bromoacetophenone and benzaldehyde. How can I prove this with the
IR spectra we obtained? What are the stretches I should note to
prove that we obtained
(E)-1-(4-bromophenyl)-3-phenylprop-2-en-1-one as our product and
benzaldehyde as our aldehyde?

How to calculate theoretical yield & actual yield for this
problem.
A student used 3 mL propanal and an equimolar amount of acetophenone as starting materials for the aldol condensation experiment. Sodium hydroxide was used for the base and ethanol was used for the solvent. After refluxing and purification, He/She obtained 3.9 g of the product.

Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...
