Organic Chemistry Essay

Oxygen-containing functional groups are the most abundant and are ultimately the most important for binding metal ions (Logan et al., 1997). The presences of functional group in organic compounds that have unshared pairs of electrons, and that can form coordinate linkages with metal ions (Fig.3) are in the order of decreasing affinity of organic groupings for metal ions as follows: -O- > NH2 > -N=N- > -COO- > -O- > C=O Enolate Amine Azo ring N Carboxylate Ether Carbonyl The order stability

The Claisen rearrangement is a [3,3] sigma tropic rearrangement. This is a class of reactions that is pericyclic. The stereochemistry is determined by the transition state (generally chair-like). Out of keto and enol, the more stable tautomer is enol. Enol is a more stable tautomer because the benzene loses aromaticity when it is in its keto form. The IR data of spectrum 1 supports this answer. The spectrum shows the OH bond, which shows an enol form. Usually, the keto form is more favorable than

Torres 1 Luis A. Torres Group #11 USC Chemistry 322b Formal Lab Report 6th November 2015 I. II. Enzymatic Resolution of 1-Phenylethanol and Diastereomer Analysis Objective/Abstract Enzymatic transesterification reaction was performed to study the resolution of diastereomers using 1H-NMR analysis. The stereo-selectivity of acylase I, an enzyme, for a 50:50 racemic mixture of 1-phenylethanol was determined. In the first of a two-step reaction, 1-phenylethanol was reacted with vinyl

drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders. Pharmaceutical drugs are often classified into groups of related drugs that have similar chemical structures, the same mechanism of action

Introduction Biochemists are scientists who study the chemistry relating to, biological organisms. It forms a bridge between biology and chemistry by studying how complex chemical reactions and chemical structures give rise to life and life's processes. Their work includes studying the complex chemical combinations and reactions involved in metabolism, reproduction, growth, and heredity. Biochemistry is sometimes viewed as a hybrid branch of organic chemistry which specializes in the chemical processes and

Hickey) Organic chemistry lab 2 manual, department of Chemistry University of New Orleans. We observed a yellow residue in the bottom of the flask after the dichloromethane has been boiled off, and 2-propanol (3ml) was added to it and then was heated until the entire residue dissolved and

8. Hydrazino-Pictet-Spengler ligation reaction = In this reaction, the aliphatic and aromatic hydrazines are used as a substrate to undergo pictet-spengler reaction with aldehydic and ketonic group. As described in the above category 7, the various substrates are used for ligation with aldehydic and ketonic groups of the proteins, P. Agarwal and research group developed the Hydrazino-Pictet-Spengler(HIPS) ligation reaction so that the stable protein conjugates can be developed . This strategy can

appetite for knowledge and understanding and I often find myself turning to chemistry for answers. For example, whilst wondering ‘what is the most expensive material’ I stumbled upon endohedral fullerenes, an organic compound worth $167 million dollars per gram, and is used in atomic clocks. It demonstrates the precise control that chemists have over the synthesis of organic compounds and the vast applications of chemistry on the real world. I am excited to continue my studies further at university

National University of Singapore CM1501 Organic Chemistry for Engineers Lab Report Experiment 2: Separation and Identification of Two Organic Compounds 10th October 2013 Abstract This experiment involves the separation and identification of 2 organic compounds (1 Neutral Compound and 1 Acidic Compound) in a mixture. Separation techniques used in this experiment include solvent extraction, simple distillation and recrystallization using a suitable solvent determined through a solubility
