Isotopes of carbon

The purpose of this report and lab was to assist in visualizing the structure of infinitesimally small objects and how they fit together. Normal object fit together similarly to microscopic atoms and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored. Copper There are a plethora of modern technological uses of copper. It can be…

iodide attacks the delta positive alpha carbon forming an intermediate that has a partially formed C-I bond and a partially broken bond between carbon and the delta negative leaving group. The stereochemistry is inverted at the alpha carbon as the C-I bond fully forms. Then the leaving group comes off of the molecule taking the electrons it shared with the alpha carbon. The reason that only 1-chlorobutane and 1-bromobutane formed a precipitate is because the carbon that bears the leaving group…

The purpose of this lab was to iodonize salicylamide and characterize the product in order to determine its structure. The crude product of this reaction was recrystallized using ethanol. The white crystalline product was isolated using vacuum filtration and characterized. The percent yield of this reaction was determined to be 39%. The observed experimental melting point of the product was determined to be 235-137 oC. When compared to the literature melting point 228 oC of the predicted product…

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…

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, indicative of information detailing the surrounding water. Most species of brachiopod shells are composed of a low-magnesium calcite, one of the most stable forms of skeletal carbonate; much less prone to diagenesis than other species. These shells are then…

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…
