Please calculate theoretical grams of if 1.10 grams where collected in part 1 and 1.08 grams where collected part 2. Also calculate percent yeild. Reaction Conditions 1 1) 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 from step 1. 3) To this mixture add 0.25 mmol of Na2CO3 dissolved in 5 mL of H₂O. 4) After 1 hr of vigorous stirring, collect the solid product using vacuum filtration and wash with H2O (3 x 10mL) and a minimal amount of cold MeOH. 5) Allow the product to dry on the vacuum, determine the yield, melting point. Reaction Conditions 2 1) 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 H₂O (3 x 10mL) and a minimal amount of cold MeOH. 6) Allow the product to dry on the vacuum, determine the yield, melting point.

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 from step 1.
3) To this mixture add 0.25 mmol of Na2CO3 dissolved in 5 mL of H₂O.
4) After 1 hr of vigorous stirring, collect the solid product using vacuum filtration and wash with
H2O (3 x 10mL) and a minimal amount of cold MeOH.
5) Allow the product to dry on the vacuum, determine the yield, melting point.
