I need help with all or whatever i can get help in!!! This is the synthesis of aspirin lab
Paragraplh Styles Synthesis of Aspirin Pre-Lab Questions Write the chemical equation for the synthesis of aspirin (ASA) from salicylic acid (SA) and acetic anhydride. Include all necessary reagents, catalysts, and 1. reaction conditions, (3 pts) In the reaction written for question # 1, circle the nucleophile Place a square around the acetyl group of the product. (2) 2. 3. Consider the mechanism given in lab. Draw a molecule of acetic anhydride indicating which C is a carbonyl carbon. Why does the carbonvl carbon of the acetic anhydride undergo nucleophilic attack? (3) 4. Calculate the theoretical yield of aspirin produced from reacting 4.25 g of salicylic acid with 8.0 ml of acetic anhydride and 10 drops of phosphoric acid. (4) 5. A student obtained 5.95 g of ASA after performing the procedure as gi the previous question. Calculate the percent yield. Is this a reasonable yield? 6. What is the function of the HsPO4 in the reaction? (2) 7 Why is ice cold water added slowly to the reaction vessel? (2) ace
