Grignard Reaction Lab Report

Improved Essays
To demonstrate their effectiveness in creating new carbon to carbon bonds, the Grignard arylation of 2-butanone was carried out. The Grignard reaction of phenyl bromide and magnesium, followed by the addition of 2- butanone yielded a crude product of 2-phenyl-2-butanol. The 1H NMR spectra was taken before distillation, showing the crude product, as well as after distillation, showing one of greater purity. In addition, an IR spectrum was taken after distillation. Both the 1H NMR and IR spectra support the conclusion that the product is 2-phenyl-2-butanol. The crude and distilled spectra show alcohol at approximately the same location; however, the peak significantly decreases in size. The IR spectra also shows a definitive alcohol peak. Due

    To begin Lab 10 of Chem 115, students received permission to start the lab procedure after completion of prelab. First, students made a 25.0 mL of a 0.15 M Malonic Acid and 0.20 M Manganese Sulfate Monohydrate solution and labeled it "Solution 1". After the solution was made, a piece of parafilm was used to seal the flask before mixing it well. Next, a 25.0 mL of a 0.20 M Potassium Iodate solution, using 0.080 M sulfuric acid as a solvent, was made. Before adding the acid, students heated about 25 mL of the acid in a 100 mL volumetric flask.…

    This lab was a two week long lab called the Grignard Reaction lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of the Grignard Reaction lab was to obtain the actual yield of the product, to calculate theoretical and percent yield of the product, and to record the melting point of the product.…

    The 1H NMR data strongly suggests that 3-pentanol was produced. On the 1H NMR, there are a total of 12H, which is the correct number of protons on 3-pentanol. Around 3.45ppm, there is a multiplet with an integration of 1. This peak corresponds to the methine proton on the carbon bearing the alcohol. The integration of 1 is correct since there is only one proton on that carbon.…

    There may have been errors in the lab that may have affected the results of the lab. There may have been mistakes: a person may have not measured the substances correctly while retrieving the liquids in the graduated cylinder, or not have been watching the conductivity probe while the group was measuring the electrolyte solution. Along with these, there is also the issue of timing the testing incorrectly. Adding onto this, there may have been a slight spill where the accurate amount of the substance being used was not completely added into the water for testing.…

    The main purpose of this experiment is to perform the Grignard reaction and synthesize, extract, purify and characterize the product of triphenylmethanol. The Grignard reagent was first synthesized using a nucleophilic addition reaction. The Grignard adduct was then hydrolyzed to form triphenylmethanol. The organic layer was extracted using diethyl ether, petroleum ether, brine and a separatory funnel. The theoretical percent yield was first calculated by finding the limiting reagent for this reaction.…

    “Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total there are five (5) chemical reactions.…

    Purpose The purpose of this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and products of a synthesis. The components were purified and dried by evaporation and vacuum filtration.…

    Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used as a flavouring agent and in perfumes. The diastereomers of the alkene are distinguished through Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy, where the coupling constants of alkenyl protons are different for (E) and (Z) isomers.4…

    One important aspect of organic chemistry is the synthesis of new compounds. It is also important for chemists to understand how to perform certain techniques, such as extraction and distillation, to produce the new products, which are usually drugs and cures for illnesses. In this experiment, n-butyl bromide was produced. n-Butyl bromide is an alkyl halide, which are usually synthesized by an alcohol and an acid. In the case of n-butyl bromide, n-butyl alcohol was used along with sodium bromide and sulfuric acid.…
