- For 20.7 the solutions for part c and d dont seem right. Shouldn't reacting with 1 eq of H2 just take away the C=C bond and not the C=O bond. (H2 reduces C=C selectively to form a ketone according to page 738. Also the both the C=C and C=O bond should be reduced if excess H2 is usedPls solve this question correctly in 5 min i will give u like for sure Balance the chemical equation of a reaction formed by the bromination of trans-cinnamic acid if we started with 0.3088 grams of trans cinnamic acid and 1mL of bromine. The product of this reaction is 2,3 - dibromo - 3- phenylpropanoic acidI am trying to calculate the theoretical & actual percent yield of amyl acetate from a Fischer reaction of 1-pentanol, H2SO4, and acetic anhydride. The final product obtained was 28.7g. Here is the information I know: 29mL of acetic anhydride was used, 5mL of H2SO4 was used as a catalyst, and (0.24mol) 26mL of 1-pentanol was used.
- During an acid base extraction of an organic compound dissolved in dichloromethane with sodium bicarbonate (NaHCO3), you do not recover any of the desired extracted product after completing all the remaining steps. What could the most probable reason(s) be for the observed outcome? -The organic compound you want to extract is also a base; an acid is needed -You did not degassed/vent the separatory funnel -You did not shake the separatory funnel enough to react the base with the organic compound -You did not heat the mixture before the extraction -The organic compound evaporate from separatory funnel during the extractionIn light of your answer to Problem 30-40, explain why a mixture of products occurs in the following reaction:5.
