Carbon copy

Distant lands, by Tim Winton is a short novel that has resonated with me as a reader by its ideas expressed on the subject matter of family, multiculturalism and human desires. This is done through the language convention: simple sentences, point of view and the actions of its main character Fat Maz. Fat Maz is the main protagonist who is used to present the idea of family that has evoked in me a sense of appreciation and gratefulness towards my parents for the things they have done for me since…

Why small covalent substances have different properties from macro molecules? • Simple covalent substances will only contain a few atoms that are held by strong covalent bonds for example co2 the molecules contain one atom of carbon that is bonded with 2 oxygen atoms. The intermolecular forces causes the small covalent structures to have a low melting/boiling points, they don’t conduct electricity because they don’t have any free electrons or an electric charge overall. • Macro molecules will…

The development of simple methods for generating molecular complexity with defined stereochemistry from easily accessible starting materials became significant and fascinating over last few decades. A simple methoxyphenol is found to be most appropriate precursor for generating wide range of complex cyclic and acyclic architectures. Several chemical1-5 and electrochemical methods6 have been used for the umpolung of electron-rich nucleophilic 2-methoxyphenols and 4-methoxyphenols to electrophilic…

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…
