Maci Mullins CHEM2130-001 12/8/2017 A Wittig Reaction of trans-Cinnamaldehyde Statement of Question: What is the stereochemistry in the Wittig product, and why is it formed? Hypothesis: There were two possible stereochemical outcomes for this experiment, either cis, (E,Z), or trans, (E,E). The cis product, (E,Z), would form if the double bond and phenyl group added to the same side. The trans product, E,E), would form if the double bond and phenyl group were to add to the opposite sides.…

was so addicting about Alcohol or what inside it made it so addicting to people, then during this semester while taking this class, I learned that the substance in beer and other alcoholic drinks that made it addicting was called ethyl alcohol or ethanol. Furthermore, I learned the reason my dad didn’t get drunk easily since before I thought that drinking three to six cans of beer would get you drunk, but I was wrong, instead three to six twelve oz drinks is around the legal…

Argument Synthesis Binge drinking and alcoholism have been a long-time concern in American society. While the government and schools have made great efforts to tackle the alcohol problems by enacting laws and providing education, the situation of dysfunctional alcohol consumption hasn’t been sufficiently improved. In the essay “Drinking Games,” author Malcolm Gladwell proves to the readers that besides the biological attributes of a drinker, the culture that the drinker lives in also influences…

Case Scenario 3: Related Case Childs v. Desormeaux, [2006] 1 SCR 643, 2006 SCC 18 (CanLII) Torts — Duty of care — Social host liability — Accident caused by guest driving his car after leaving party intoxicated — Whether social host owes duty of care to third parties who may be injured by intoxicated guest. After leaving a party held in a private home, D, who was then impaired, drove his vehicle into oncoming traffic and collided head‑on with another vehicle. One of the passengers in the…

How was the Volstead Act applied to American citizens differently for the African American then the White Americans? It was January 17, 1920 around 12:01 am, when the United States of American enacted the Volstead Act, make the US officially “dry.” The 18th amendment which was ratified in 1919, but enacted in 1920, outlawed the transportation, sale, or manufacture of any intoxicating liquor from or to the United States of American. Throughout our history, the ratification and enactment of the…

Wang et al. (2015) formulated a solid dispersion to improve the solubility and bioavailability of Ginkgo biloba extract (GE) through hot melt technology. The polymer studied were Kollidon® VA64/Kolliphor® RH40 (85:15) and the extrusion was carried out at 120-125⁰C with 100 RPM with 25% drug load. DSC and XRD studies confirmed the amorphous conversion of the GE and the dissolution carried in 250ml of 0.1N HCl showed that the dissolution of solid dispersion of GE was significantly improved (2-3…

1.2.2. Physical Properties Methyl ethyl ketone is a clear, colourless fluid that is less viscous than water and has a somewhat acute odor that smells most of the ketones and is described by some as being similar to Boerscot. Compared with acetone it is less volatile and less soluble in water (about 27.5g / 100mL at room temperature). It is a solvent used for extracting gums and oils from plants and cleaning the remnants of metal and glass, so why often a cleaner or ingredient is found 1.2.3.…

Microwave (MW) assisted Esterification of Benzoic Acid (BA) offers the advantage of transformation of energy and heating throughout the volume efficiently in a shorter period and eliminates the use of excess solvent, during the course of reaction. The present study aims to assess the conversion and selectivity for the production of methyl benzoate compounds by esterification of benzoic acid using microwave irradiation. Effects of operating parameters such as reaction time, feed composition,…

Aims of Experiment 1. To extract benzoic acid from the toluene-benzoic acid mixture, using oxidation-reduction reaction (chemical properties) and difference of solubility (physical properties) –Expt. 1 2. To learn how to recrystallize the solid organic compounds well for getting more purified compounds –Expt. 2 3. To find which differences between raw product and recrystallized product are observed. –Expt. 2 4. To determine melting point range of organic compounds with digital melting point…
