Nasra Hussein Dr. Carolyn Wanamaker CHE 222: Organic Chemistry 2 January 29, 2016 “Conversion of Oxazolidinediones to Isoindoloisoquinolinones via Intramolecular Friedel-Crafts Reaction” Researchers Ji-Young Min and Guncheol Kim from the Department of Chemistry at Chungnam National University developed a method of converting isoindoloisoquinolinones using a Friedel-Crafts reactions. Friedel-Crafts are reactions that involve a 2-step substitution mechanism where substituents are attached to…

the peak at around δ = 0.9 ppm.31 The proton of −CH2− groups of the fatty acid backbone and terminal methyl group attached proton show the peak between δ =1.20−1.59 ppm.30 The peak at δ = 5.4 ppm is attributed to the protons attached to the olefinic carbon atom (−CH=CH−) of fatty acid,28 this peak provides the evidence of the presence of fatty acid chain of SO in the HBA resin. The peak in the range δ =7.3−7.5 ppm associated with the aromatic protons attached to the benzene ring of phthalic…

Common Core Task: Argumentative Essay Synthetics or Real Diamonds “Shine bright like a diamond.” Diamonds have been used for engagement rings for a long time. The diamonds are difficult to find which, shows the importance of them. But, their are also, synthetic diamonds which, are man-made in a lab. Instead, of diamonds that take years to make. In the article, Engineered Diamonds it states,” Diamond is the hardest naturally occurring material found on Earth.” So, real…

TASK 4 CORRELATING STRUCTURE ACTIVITY RELATIONSHIPS Task 4 aims to develop knowledge of the relationship between the structure of ENMs and their toxicity. In this study, different kinds of metal oxide nanoparticles, carbon nanotubes, and graphenes will be tested their toxicities and then their structures and their toxicities will be found their correlations. For MONMs, different coatings of ZnO will be tested toxicities and observed the relationships, while differences in their sizes and…

I. Diamonds are crystals made of a chemical called carbon. They are the hardest known natural material in the world, and one of the most valuable. In the Greek language, the word diamond means indestructible. It is possible to create diamonds with carbon and by applying extreme heat and pressure. Diamonds are measured in carats; one carat is two-hundred milligrams. Diamonds are better conductors then any other metal in the world, four times better than copper. Time, money, and extreme heat and…

Brachiopods within the fossil record have many uses to help inform us about past seawater evolution. As they were one of the earliest animals after the Cambrian explosion to develop a hard skeleton, they have a strong presence in the fossil record throughout geologic time and are the subject of one of the preferred methods used for deep time isotopes. As the calcite within the hard shell of a brachiopod precipitates out of the surrounding seawater, trace elements are recorded within the shell,…

n.d. ). When these two chemical are mixed they immediately react with each other. During and after the reaction carbon dioxide gas is produced. The bubbling and fizzing created by the chemical reaction is the carbon dioxide( Apple Cider Vinegar, n.d. ). This makes it a perfect extinguisher for putting out fire because the carbon dioxide can be used to suffocate the fire. Since carbon dioxide is more dense than the air surrounding the…

Today midian wants to give you a reason to read and to show science is not boring so please read. this 4 paragraph paper about molecules and what are they?They are cool genes we wear and they are cool to show off so sit back enjoy and thank you. 1# The first molecule is carbohydrates it's kinda of a sugar molecule the carbohydrates let your body talk to each other to keep you going. It's basically seen in sugar and they are made of a tiny little other substance called atoms. one sugar…

Strontium Isotope ratios are used in archaeology to track human migration.86Sr abundance is constant, but 87Sr forms through decay of 87Rb in rock. Rock age and initial Rb/Sr ratios vary geographically, making87Sr/86Sr a location tracer. Strontium, weathered from bedrock into groundwater then taken up by flora and fauna, can substitute for Ca in tooth enamel. Enamel only forms during childhood, specifically the early first and second molars mineralize during early childhood; the third molar…

This is two week project is to evaluate the stereochemical outcome and facial selectivity of an oxidation-reduction interconversion between 4-tert- butylcyclohexanol and 4-tert-butylcyclohexanone while investigating the stereoselectivity of different reducing agents. During the first week, 4-tert-butylcyclohexanol, a secondary alcohol (mixture of cis and trans stereoisomers) is to be oxidized into a ketone, 4-tert-butylcyclohexanone using sodium hypochlorite (bleach). Thin layer chromatography…
