Can you explain how to find what is the theoretical yield, and the desired percent yield of ethyl 4-nitrobenzoate? 1. Synthesis of ethyl 4-nitrobenzoate a) In a 50-ml round-bottom flask, weigh out 4-nitrobenzoic acid (0.85 g, 0.005 mol). Add to this 8 ml of absolute ethanol. Add boiling stones, and then bring this solution to the Lab Technologist. WATER OUT b) The Lab Technologist will deliver 1.2 ml of concentrated sulfuric acid to the mixture from the automatic pipette. [CAUTION,...
Methanol and water mixtures were found to be suitable for recrystallization based upon solubility test results for the reaction product mix. Explain why this might not be a good idea besides the yield may suffer (why?) or mixed solvents are difficult to work with. Here are the procedures for the lab if this helps: Synthesis of Nitrated Phenylacetic Acid The instructor will assign each student to either 90% fuming nitric acid or 70% nitric acid. **** 90% fuming nitric acid...
