Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

al Chain Reactions: Bromination of Arenes Introduction The purpose of the bromination of arenes was to determine the different reactivities of different hydrocarbons with different hydrogen atoms when reacted with bromine under free-radical substitution. The time it took for the bromine color to disappear was used to determine the order of reactivity of the different hydrocarbons. Data and Results The data of the 10 hydrocarbon tubes and the 2 control tubes with bromine and dichloromethane in

Ibuprofen and Acetaminophen Organic chemical compounds contain a vast number of isomers‚ molecules with the same molecular formula but different atomic arrangement‚ of which there are three types: structural‚ geometric and optical. The most closely-linked of isomers are optical isomers‚ which differ only by the three-dimensional placement of the molecule’s attachments‚ which renders its mirror images to be non-superimposable. The presence of optical isomerism within a molecule is determined by

Mohamad Diab Reaction Of Alcohols Purpose: The following experiment will study the chemical reactions of a selection of alcohols to determine the effect of the position of the OH functional group in the molecule. Hypothesis: Suppose that the primary and secondary alcohols will react with HCL and KmnO4‚ and the tertiary alcohol wont react with either HCL nor KMnO4 due to the location of the OH. The carbon that is bonded to the OH in both primary and secondary still has one or two Hydrogen
