Reaction Conditions 1 1. In a 50-mL round-bottomed flask, with a spin bar, add 10mL of H20 solution which contains 1.0 2. mmol of 2-acetylpyridine. Stir the mixture vigorously. 3. Place 1.0 mmol of 4-nitrobenzaldehyde in a separate vial and dissolve using a minimum amount of warm MeOH. While still warm, add the solution of 4-nitrobenzaldehyde to the stirring mixture in the round-bottomed flask. 4. To this mixture add 0.25 mmol of Na,CO, dissolved in 5 mL of H,O. 5. After 1 hr of vigorous stirring, collect the solid product using vacuum filtration and wash with H,0 (3 x 10mL) and a minimal amount of cold MeOH. 6. Allow the product to dry on the vacuum, determine the yield, melting point and record the IR 7. spectra of your product. ceaction Conditions 2 . In a 50-mL round-bottomed flask, with a spin bar, add 10mL of H2O solution which contains 1.0 mmol of 2-acetylpyridine. Stir the mixture vigorously. 2. Place 1.0 mmol of 4-nitrobenzaldehyde in a separate vial and dissolve using a minimum amount of warm MeOH. While still warm, add the solution of 4-nitrobenzaldehyde to the stirring mixture in the round-bottomed flask. 3. To this mixture add 0.25 mmol of Na2CO3 dissolved in 5 mL of H2O. 4. Attach a water-cooled reflux condenser and heat the reaction to reflux using an oil bath or a heating mantle. 5. After 1 hr of vigorous stirring at reflux, cool the reaction using an ice-water bath, collect the solid product using vacuum filtration. Wash the solid with H20 (3 x 10mL) and a minimal amount of cold MeOH. 6. Allow the product to dry on the vacuum, determine the yield, melting point and record the IR spectra of your product. Cleanup: All of the filtrate waste should be placed into the organic waste container. Vhat was the main difference between the experimental reaction conditions 1 and 2? Select one: a. water b. warm methanol C. stirring d. sodium carbonate e. time of reaction f. refluxing
