Bromination Of Cyclohexene Lab Report

820 Words4 Pages

Introduction The bromination of cyclohexene is a classical organic chemistry experiment designed to elucidate the addition of bromine to alkenes. This reaction entails the addition of an electrophilic electron promoter across a carbon-carbon double bond, and the formation of vicinal dibromide. Scheme 1 indicates the net reaction. During the process of the experiment, different analytic methods were implemented to distinguish the reaction product, such as gas chromatography (GC), thin layer chromatography (TLC), and infrared (IR) spectroscopy.

The course of bromination of cyclohexene was studied and characterized through spectrometry techniques (IR), thin-layer chromatography (TLC) and GC-MS. The goal had been to be able to synthesize 1,2-dibromocyclohexane, but the presence of many different peaks in the GC and spots on the TLC plate, resulted in the straightforward conclusion that most likely by products or the incomplete reaction had been formed.The results of the …show more content…

The regional alcohol next in order, 1-bromocyclohexane, also satisfies the data of GC-MS and confirms the existence of partially brominated alkyl compound. This suggests that the adaption is cyclohexene, a likely unused substance. Nonetheless, the absence of an Rf value restricts quantitative interpretation; however, it is possible to deduce that one of the poles experienced the reaction as well as the kinetics of the

A white solid was formed as a product with 59.3% yield. In this reaction tetraphenylcyclopentadienone used as the diene, which was condensed with a highly reactive alkyne dienophile (diphenylacetylene). Heat was used to overcome the diene’s enhanced activation energy. The mixture turned dark brown indicated the loss of carbon monoxide, which made this reaction, overall, irreversible. The result was formation of a high yield hexaphenylbenzene which is more stable than the first product, The Reason is that the delocalized electrons in the rings give more stability to hexaphenylbenzene as compared to the dimethyl

The product obtained was (2S, 3R)-2, 3-dibromo-3-phenylpropanoic acid and (2R, 3S)-2, 3-dibromo-3-phenylpropanoic acid, which are enantiomers. This was determined through melting point analysis. The melting point range for the product was 198 to 202 degrees Celsius, which is a lot close to the given melting point of the anti-addition product, 202-204 degrees Celsius. The given melting point range was 93.5-95 degrees Celsius. Furthermore, the syn-addition product is unlikely and difficult to produce due to stereochemistry selectivity.

Dehydration Of 2-Methylcyclohexanol Lab Report

Dehydration of 2-Methylcyclohexanol Sura Abedali Wednesday 2:00 PM January 31, 2018 Introduction: Dehydration reactions are important processes to convert alcohols into alkenes. It is a type of elimination reaction that removes an “-OH” group from one carbon molecule and a hydrogen from a neighboring carbon, thus releasing them as a water molecule (H2O) and forming a pi bond between the two carbons1. In this experiment, 2-methylcyclohexanol undergoes dehydration to form three possible products: methylenecylcohexane, 1-methylcyclohexene, and 3-methylcyclohexene in a Hickman still apparatus. Adding 85% Phosphoric Acid to protonates the “-OH” group, turning it into a better leaving group and initiating the dehydration reaction.

April 16, 2024 Bromination of E-Stilbene Report Abstract Alkenes, due to the presence of C=C bonds, are prone to electrophilic addition reactions. this experiment aims to break the central C=C bond in E-stilbene and add bromine to those carbons. We will do so by dissolving solid E-Stilbene in dichloromethane (DCM) and adding liquid bromine. Since excess bromine is being used, we use sodium thiosulfate to remove it from the solution and separate in the separatory funnel. We then ice the dibromostilbene crystals, vacuum the solvent, and dry to obtain the sample.

Experiment 7A: Carbonyl Reduction: Sodium Borohydride Reduction of 4-tert-Butylcyclohexanone Experiment 7A, Carbonyl Reduction: Sodium Borohydride Reduction of 4-tert-Butylcyclohexanone, provides firsthand experience with carbonyl reductions. NaBH4, a mild reducing agent, was used to reduce the ketone functional group in the compound, 4-tert-Butylcyclohexanone, that was then protonated using hydrochloric acid to produce two diastereomers (cis/trans) of 4-tertbutylcyclohexanol. Moreover, this experiment refined skills in using H-NMRs (integration, multiplicity, and coupling constants) to effectively distinguish between cis and trans isomers of a desired product. To begin the experiment, 50 mg of 4-t-butylcyclohexanone and methanol were added to a conical vial. NaBH4 was then added to the reaction mixture to reduce the ketone functional group (present in the starting material).

Bromohexane Lab Report

The goal of the experiment is to synthesize a bromohexane compound from 1-hexene and HBr(aq) under reflux conditions and use the silver nitrate and sodium iodide tests to determine if the product is a primary or secondary hydrocarbon. The heterogeneous reaction mixture contains 1-hexene, 48% HBr(aq), and tetrabutylammonium bromide and was heated to under reflux conditions. Heating under reflux means that the reaction mixture is heated at its boiling point so that the reaction can proceed at a faster rate. The attached reflux condenser allows volatile substances to return to the reaction flask so that no material is lost. Since alkenes are immiscible with concentrated HBr, tetrabutylammonium bromide is used as a phase-transfer catalyst.

Initial Results and Interpretation After testing whether the experiment ran the whole way on a TLC plate , it was determined that there were distinct differences among the co-spots and mixtures. Because of this, Para-fluorobenzaldehyde and acetophenone were chosen based on the results from the TLC plate as seen in figure three. The spots showed that the reaction ran to completion as the starting material, acetophenone and the final product had distinctly different RF values. As a result, this helped support the initial hypothesis that was made due to the

From this reaction, only 0.113g (94.9% yield) of 4-bromoacetanilide was collected. When the solution was transferred to the Buchner funnel, some product got stocked in the small tube. The spatula was used to get the most of the mas of final product. Losing this small amount of the product caused the decreasing of the percent yield. By taking the melting point of this solution, it was confirmed that 4-bromoacetanilide was only formed.

In Figure 1, Distillate 1 appears constant with a slight increase between 76 ° C to 78 ° C. As a result, 12.381 % of the gas chromatography evaluation of Fraction 1 was toluene. For the gas chromatography results of Fraction 2, in which Figure 1 shows the temperature continuously increases; that denotes that there was a mixture of two components. As a result, 75.912% of the sample obtained was cyclohexane, and the rest was toluene. If the collection of Distillate 2 was taken earlier, the amount of toluene would be closer to the amount of cyclohexane. For Distillate 3, the temperature appears constant in Figure 1.

Carefully, 15-20g of pre-cooled cyclohexane was poured into the freezing-point tube, the tube recorked, and the whole thing was reweighed, to find the exact mass of the cyclohexane. The dry thermistor and stirrer were inserted into the FP tube, ensuring they were immersed in the liquid. A large beaker was filled with ice and water, which the FP tube was placed into. The cooling curve was determined by recording the temperature at regular time intervals (every fifteen seconds) as the cyclohexane cooled, until the temperature became constant. The cyclohexane was stirred continuously.
