How do you construct a flow chart using extraction to separate a mixture of the 3 solids used below if dicholoromethane is the solvent and any other reagents can be used. The 3 solids are: pyrazole, p-chlorobenzoic acid, and benzophenone.

1. Why does 1-butanol and cyclohexanol are immiscible whereas 2-methylpropanol and ethylene glycol are miscible? 2. What is the oxidation product of methanol inside the body and why is it harmful? 3. Write your observation based on the acidic properties of each sample Sample Observation 1-butanol   2-butanol   2-methyl-propanol

Question 1 You are employed as a co-op student at the Drug and Alcohol Testing Association of Canada (DATAC) developing analytical tests for sports doping agents. You are asked to prepare a procedure for the extraction of methylphenidate, the active compound in Ritalin, from urine samples (consider them as simple aqueous layers, you do not need to consider other components!). The goal of the procedure is to extract the methylphenidate into an organic layer which will then be evaporated and the residue will be tested for the drug. You find that methylphenidate is highly soluble in 2-methyltetrahydrofuran, a bio-renewable solvent. Draw the structure of 2-methyltetrahydrofuran and give two reasons why it is a good solvent choice for liquid-liquid extraction. (Please find the image attached below to help you with this question) Question 2 (cont. from scenario 1). Your colleague is helping you develop the urine test. They suggest that the urine should be adjusted to a pH above 7 before…
