Benzene

example, Friedrich Kekule’ that had fallen into the trance on top of a bus and seen chains of carbon atoms dancing around wildly and then saw one of the carbon chains put its tail in its mouth, forming a ring. This was how he ended up discovering the benzene ring which led to the revolutionizing of…

Zara Beadle METR 113 24 November 15 Assignment #4 SF Bay Area Air Pollution Risk Assessment The Bay Area Air Quality Management District (BAAQMD) is an agency responsible for air pollution control in the San Francisco Bay Area. The BAAQMD is devoted to improving air quality and public health to all Bay Area citizens. Communities in the SF Bay Area that have the highest health risk from air pollution are Concord, Eastern San Francisco, Western Alameda County, Redwood City/East Palo Alto,…

Since suitable crystals for X-ray single crystal analysis was not obtained, to have reliable structural information, HR-TEM analysis of the product was carried out. The average size of the assembly calculated from HR-TEM measurement is found to be 2.8 nm which is in good agreement with the size of the previously reported Pd6L8 assembly where L is the non N-methylated (2.5nm, Fig. 2).9 As first step, to explore the catalytic activity of 1 in copper and phosphine free Sonogashira coupling reaction…

Most of us have had the chance to taste a nice cold, sweet, bubbly sensation in our mouths from soda. There is no denying it’s taste is addictive and refreshing, but at what cost? There is a lot of controversy around the subject of soda and it’s effects, and if it should be taxed or not. This essay will explore if a tax on soft drinks is warranted. It would need to be efficient, fair and effective. This report will look at how these criteria can be met, and how taxing soft drinks have an effect…

Leukemia is a cancer of the blood, the complex disease occurs when there is too many white blood cells present or cancer cells are in the bone marrow. Leukemia is a Greek word that is broken down into leuko which means white and haima meaning blood. Peter Cullen found incomprehensibly what was called “milky blood” early in 1811. In 1825, Alfred Velpeau discovered the symptoms of Leukemia and found pus in the blood of patients. During the 19th century, the disease was first named weisses blut…

group of 4-aminophenol is acetylated by acetic anhydride to produce paracetamol and the by-product of the reaction, acetic acid. Paracetamol is contains three functional groups; A hydroxyl group (OH), an amide group (HN-CO-R) and an aromatic group (benzene ring).…

NRE- 155 Course Title: Environmental Law and Policy Course Coordinator: Mr. M V Shiju Documentary review- GASLAND Directed by-JOSH FOX United States of America, the superpower is stated as an example whenever we discuss how governance should play its role in people’s welfare. Gasland is an outcome of the letter Josh Fox received by a natural gas company to drill in his backyard. This documentary can be an eye opener or a setback for all those who think that it’s just the developing…

A possible chemical reason that this experiment yielded less than 100% triphenylcarbinol was caused by the Grignard reagent reacting with atmospheric water or oxygen instead of reacting with benzophenone due to the highly reactive nature of the Grignard reagent and a constant presence of humidity and moisture inside the laboratory. Although extra precautions were taken to dry to glassware and a CaCl2 drying tube was used, there was an unavoidable exposure of the Grignard reagent to atmospheric…

Abstract The primary goal for this laboratory experiment was to synthesize, purify, and identify p-nitroacetanilide using acetanilide as the starting material. To test for the purity and identification of our desired product, we gathered data from: Thin Layer Chromatography (TLC), Melting Point (MP) range, Infrared (IR) spectrum, Gas Chromatography Mass Spectroscopy (GC-MS), and Proton Nuclear Magnetic Resonance (1H NMR). TLC plate indicated the formation of our pure product due to the…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…
