**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 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.

Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?

In this lab you are performing your first organic synthesis and safety information on all the materials you are using must be obtained. Companies are required to provide material safety data sheets (MSDS) for chemical compounds they sell. Please examine the MSDS for salicylic acid, available here. You will find GHS pictograms within the sheet that summarize the main hazards of this compound. The pictograms are essentially the same as the symbols on WHMIS labels, available here for reference. Based on the pictograms, whatare the main hazards for salicylic acid? Select as many answers as appropriate Select one or more: Acute oral or inhalation toxicity Flammable material Carcinogen Self-reactive substance Gas under pressure Corrosive Oxidizing material
