Experiment 11: Synthesis of Aspirin pre-lab (4 pts) 1) (2 pts) Refer to the introduction on interpreting the ferric chloride test for phenols. Two students performed the aspirin synthesis experiment. Their melting point and ferric chloride test data are shown below. Based on the results, which student's aspirin has the higher purity? Justify your choice using the melting point data and ferric chloride test results. Melting point range for pure aspirin = 136-140 °C. Melting point range (°C) Ferric chloride...

EXPERIMENT 20 CSI: SMU Part 2. Synthesis of an Ester. Esters are compounds of the form RCOOR'. They occur naturally in many plants and animals, and can be synthesized. They have a pleasant aroma usually described as "fruity of flowery". In a Fisher esterification an ester is formed from the reaction of a carboxylic acid and an alcohol with a strong acid as a catalyst. The OH contained in the carboxylic acid group 1s replaced with the alkoxy group (O-R")...
