In the reaction mechanism‚ a carboxylic acid‚ m-toluic acid is used to synthesize N‚N-diethyl-m-toluamide‚ also know as DEET‚ through a nucleophilic acyl substitution reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a

A Diels-Alder Reaction History and Application: The 1950 Nobel prize in chemistry was awarded to Otto Paul Hermann Diels and Kurt Alder for their breakthrough work on the discovery and development of [4 + 2] cycloaddition reactions i. This set of reactions are enormously useful in the synthesis of six membered rings in a single stepii. These are used in many pharmaceutical applications. Tamiflu® is a drug which

Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

Melting point 1. What two effects do impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid

Linkage isomerism in cobalt(III) complexes Author: M Hurley Abstract Preparation of nitrito-kO-complex was prepared by ligand substitution from a chloridio-complex chemically made. The nitro-kN-complex was then prepared by isomerisation of the nitrito-kO-complex. Visible absorption and infrared spectroscopy was then carried out on all three complexes. The molar absorption coefficients calculated were 38.0 cm-1 mol-1 L for the chloridio-complex‚ 76.0 cm-1 mol-1 L for the nitrito-kO-complex

A CASE STUDY ON THE EVOLUTION OF MOSQUITO REPELLENTS By:- Rajdeep Laha Calcutta Business School PGDM 2010-12 OVERVIEW Traditionally‚ various types of substances have been used to repel mosquitos. These include such things as smoke‚ plant extracts‚ oils‚ tars‚ and muds. As insect repellent technology became more sophisticated‚ individual compounds were discovered and isolated. This allowed the formulation of new‚ more efficient forms of mosquito repellents. The first truly effective

Substance abuse- Inhalants The term substance refers to chemical compound that are ingested in order to alter mood or behavior. Substance use: It is the ingestion of psycho active substance (which alters mood or behavior) in moderate amount that does not significantly interfere with social‚ educational or occupational functioning. Eg: Drinking a cup of coffee in the morning in order to wake up. Substance intoxication: It means our physiological reaction to ingested substances that is getting high
