**Question 2: Explanation for a Negative Iron(III) Test with Eugenol**Eugenol is a naturally occurring compound often used in the fragrance and flavoring industries. When performing an iron(III) chloride test, it typically results in a color change indicating the presence of phenolic compounds. A negative result, meaning no significant color change, suggests the absence or insufficiency of such compounds in the test sample, or that the sample contains interfering substances. Additionally, consider whether the test was conducted under appropriate conditions regarding concentration and pH, which can affect the outcome.

Ferric Chloride test is performed to detect the presence of phenols, especially in natural extracts…

Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.

Question #2
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.

Part A The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. The forensic technician at a crime scene has just prepared a luminol stock solution by adding 15.0 g of luminol into a total volume of 75.0 mL of H2O. What is the molarity of the stock solution of luminol? Express your answer with the appropriate units. Luminol has a molecular weight of 177 g/mol. • View Available Hint(s) HẢ molarity of luminol solution = Value Units Submit Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 6.00x10-2 M.

Given the procedure below to synthesize aspirin, where 30% yield was obtained, what are possible reasons for the lower yield and would this be an effective method to sythesize aspirin on a large scale? Weigh about 2 g of salicylic acid. Record the mass to the nearest milligram. Transfer the solid to a large test tube. Label the test tube. • Carefully add about 4 mL of acetic anhydride to the test tube containing salicylic acid using a 10 mL graduated cylinder. Gently mix the contents, avoiding any spilling of the liquid. Most of the solid will not dissolve at room temperature. • Carefully add about 5 drops of concentrated sulfuric acid to the mixture. Gently swirl to mix the sulfuric acid. • Place your labeled test tube in the hot water bath. After about 1 minute, swirl the contents of the large test tube to dissolve any salicylic acid that was not dissolved initially. Leave the test tube in the hot water bath for about 15 – 20 min. • While the sample is being heated, fill one-fourth…
The purity of the aspirin sample is tested with iron (III) chloride. A purple color resulting from iron (III) chloride test indicates the aspirin sample contains some unreacted salicylic acid and the carboxylic acid group in salicylic acid gives a purple color. the structure of aspirin itself contains a phenolic -OH group. O the aspirin sample contains some unreacted salicylic acid and the phenolic -OH group in salicylic acid gives a purple color. the aspirin sample contains some unreacted salicylic acid and the ring structure in salicylic acid gives a purple color.
