Question

Analysis Questions 1. Given the structure of an aldehyde and a ketone, predict the structure of the reaction product. Use the table below to practice and to predict the possible products your class synthesized. HẠC CHỊ acetone cyclopentanone benzaldehyde Product #1, m.p. 113 °C Product #2, m.p. 189 °C NA trans-cinnamaldehyde Product #3, m.p. 144 °C 2. Include the IR spectrum of your product. Label important peaks with corresponding functional group. 3. Include the melting point your product. 4. Draw out the mechanism for the reactants you used. Include the keto-enol resonance structures. 5. Calculate theoretical yield and percent yield. Show all your work for full credit. 6. Were you successful in your synthesis? How pure is your product? Use IR spectra and melting point to justify your answer. 7. If your reaction was not successful, trouble shoot and explain what you would do differently to get the expected product. If you were successful, what would you do to increase your percent yield?

Answer 1

Here, I am giving product wise answers. i.e each and every product's reaction, mechanism, IR spectrum and melting points.

Here IR spectrum is not to scale. we are showing major peaks regarding the products.
