Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product.

Experiment #7 Introduction In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process had worked we employed: IR spectra analysis‚ column chromatography‚ and a little TLC. This experiment is relevant

therapeutic use of essential oils and to know what aromatherapy is‚ one must know that essential oils are the steam distillates derived from the aromatic plants (Freeman‚ 2009). Aromatherapy dates back to the era in which medicine was first discovered and can be labeled as preventative care. It is said that Hippocrates stated that “the way to health is an aromatic bath and a scented massage every day”. This wordage indicates that preventative care was also meant to go hand in hand with the medical field

at a molecular level of cigarette smoke and other risk factors that causes lung cancer‚ all these smokes and gases contain several carcinogenic components. The most carcinogenic components in cigarette smoke are benzo[a]pyrene (BaP)‚ a polycyclic aromatic hydrocarbon‚ and nitrosamine (10). BaP is activated by the phase I enzymes that are responsible for the metabolism of xenobiotics‚ the cytochrome P450 enzymes (CYPs) (13). CYPs detoxify a wide variety of xenobiotics but also is an enzyme that provides

nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore means that the compound is an aromatic compound. This is an aromatic compound because the compound consists of six carbons of benzene joined in a ring‚ having the planar geometry of a regular hexagon in which the distance between all of the C-C bonds are equal. The compound has three different isomers

Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

Friedel-Crafts liquid phase alkylation reaction of aromatic compounds is an industrially important which is known since 1877 and also commonly practiced in organic chemistry for the synthesis of various pharmaceutical compounds [1]. Catalytic benzylation of aromatics with benzyl chloride is one of the commercially significant C-C bond synthetic reaction processes to produce benzylated aromatics such as diphenylmethane and substituted diphenylmethanes. These are key intermediates in the synthesis
