POST-LAB QUESTIONS 1. Excess acetic anhydride is destroyed by adding water after completion of the reaction. Write out the chemical reaction. Use structures, not just formulas.
Friedel-Crafts Acylation of Ferrocene lab. During workup of the product, water reacts with the excess acetic anhydride to give what side product(s)? #6 FRIEDEL-CRAFTS ACYLATION OF FERROCENE H3PO4 DISCUSSION 1. During workup of the product, water reacts with the excess acetic anhydride to give what side product(s)?
Draw a structural formula for the symmetrical acid anhydride that forms from butanoic acid. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. . с opy P C CHE ChemDoodle
Geometric isomer lab Maleic Anhydride: 5.00g Maleic Acid: 1.59g Impure Fumaric: 1.37g Pure Fumaric: 1.04g Give each structure drawings to demonstrate that maleic and fumaric acid displays intermolecular H-bonding. Explain the difference in the melting points of maleic and fumaric acids by the difference in their H-bonding.
4. A laboratory procedure calls for 0.146 g of acetic anhydride. Calculate the volume of this reagent needed in the reaction.
Procedure and Post-Lab: both the Procedure and the Post-Lab go together in this lab. After performing each of the indicated tests, answer the questions before moving on. This lab report is due at the end of the lab period today. Questions 1) The blood pH is carefully maintained within the range of 7.35 to 7.45. Based on this information, is the pH of blood acidic, basic, or neutral? Briefly explain your reasoning. (2 pts) 2 A patient has their blood...
What does anhydride mean? What would happen to the acetic anhydride if water was present in the reaction mixture? How would this affect the yield of the aspirin reaction? 1.
What is the importance of symmetrical components in fault studies? Give an illustrative example (with computation) on the comparison of solving three phase fault using symmetrical components and without symmetrical components.
Excess acetic anhydride is destroyed by the addition of water, which converts the anhydride into acetic acid. Write the balance equation for the reaction FeCl3 is used to test for the presence of unreacted salicylic acid. Write the neutralization reaction of salicylic acid with NaOH to produce sodium salicylate.
Assume that you were assigned BaCl_2 in lab. Your water weighed 20.343 g. Following the procedure in the lab manual, you determined that freezing point of water is 0.16 degree C. You weighed 1.120 g of salt and determined that the freezing point was -0.38 degree C. Based on these experimental parameters, calculate the van't Hoff factor for BaCl_2. Note that these are made-up numbers, and do not reflect a true experiment. **Molality is moles of solute per kilogram of...
