of t-Butyl-Chloride March 8 & 15‚ 2012 Theory: Alkyl halides can be synthesized when alcohols react with hydrogen halides. An alkyl halide is a halogen-substituted alkane‚ and a hydrogen halide is a compound consisting of a hydrogen bonded to a halogen (H-X). Alkyl halides are classified as primary‚ secondary‚ or tertiary depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare t-butyl-chloride

Investigative question: how are esters formed ? Esters are formed by the reaction of an alcohol and a carboxylic acid‚ usually in the presence of sulphuric acid to catalyse the process‚ or by the reaction of an acyl chloride with a carboxylic acid (this requires no catalyst and is irreversible without additional reactants) are the most common ways used. Others include reactions of certain molecules such as structural rearrangement. Apparatus: Plastic dropping pipettes‚ Beaker (100 cm3 or 250

In this experiment‚ the objective is to successfully perform an SN1 reaction to determine the reactivity of tert-butyl chloride‚ through the usage of sodium iodide/silver nitrate reagents and to synthesize tert-butyl chloride. The tert-butyl chloride was synthesized through the use of separation (aqueous and organic layers) and distillation. Tert-butyl chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

Book of Esther Review 1. (Source Sheet 1‚ #5) For the first time‚ there are two major Jewish communities: one in Persia and one in Eretz Yisrael. There is a tension between the two communities. The community in Persia is assimilated and they were high up in status. The two communities do not mention one another; there is no mention of Shushan in any of the books of the people who lived in EY. In Persia‚ the Jews were very assimilated - the Jews intermarried and were economically very well off

The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously

of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1.
