Alkene

Olefin Metathesis Introduction: Alkenes—referred to as olefins due to their oil forming tendency with chlorine—play an important role in the production of polymers. The work by Ziegler and Natta on the catalysts for polymerization of alkenes established the roots of the polymer industry. However, a major catalyst to its growth was the great discovery made by Grubbs, Schrock and Chauvin that won them the Nobel Prize in Chemistry in 2005—olefin metathesis. Olefin metathesis refers to a reaction involving

The dehydration of 2-methyl-2-butanol was performed using sulfuric acid and phosphoric acid in order to synthesize alkene products 2-methyl-1-butene and 2-methyl-2-butene. After carrying out steam distillation to isolate the organic alkenes from aqueous components within the reaction mixture, the purity and characterization of the products were then assessed through various analytical methods including Gas Chromatography (GC), Infrared Radiation (IR) Spectroscopy, and Nuclear Magnetic Resonance (NMR)

During this process an intermediate carbocation is formed as shown in the figure above. A base then removes the proton adjacent to carbocation leading to the formation of an alkene. Since heat, concentrated sulfuric acid and phosphoric acid were used during this experiment, the result is an alkene and water (dehydration reaction). After the experiment was conducted, the mass of the product was first taken in order to calculate the percent yield of the experiment. Since the reactant

sodium sulfate was added and not for long enough. These results were confirmed by the quality tests that showed that a precipitate formed when KMnO4 was added to the solution and in the IR spectroscopy peaks showed peaks at 3022.62cm-1 which matches an alkene, further showing that the formation of 3-methylcyclohexene was successful with a percent yield of 56.46%. Introduction: The major reaction that happened was an E1 reaction (otherwise known as a unimolecular elimination reaction). In this reaction

Overall, the experiment went smoothly. Our product’s identity and purity was tested by calculating the density, an alkene test using Bromine Water, and conducting both an IR and a H-NMR spectra. The first test that was conducted was comparing densities between our product and the known density of Limonene. From our data, our product had a density of 0.815 g/mL, which is only 0.027 g/mL off from Limonene’s known density of 0.842 g/mL. Our density may even be closer due to the inaccuracy of having

Introduction To transition from an alcohol to an alkene, the alcohol must be dehydrated with the help of an acid through a reaction known as an E1 mechanism.1 The first step of an E1 reaction is the formation of a carbocation intermediate. This carbocation is produced by the removal of a halogen or a substituted group.2 In this experiment, the hydroxy (OH ) group of the alcohol is removed and this produces the carbocation. The OH- group is removed due to the presence of phosphoric acid. The phosphoric

get to see or realize that where n how we having our life much easier than it used to be. In these writing assignments, the topic is about the organic chemistry. In organic chemistry, we all have different kinds of compounds. In addition, alkanes, alkenes, and alkynes are the parts of the organic and inorganic compounds. We also can learn about the structural formula they all have in different form. Polymerization is another type of chemical reaction that we get to

the sink? -All chemicals used are harmful to aquatic life and should not be allowed to enter the drains, thus need to be disposed of through the lab technicians. Aim To investigate the differences in reactivity between alkane and alkene hydrocarbons. Hypothesis Cyclohexene will be more reactive than the cyclohexane as it has a double bond. The cyclohexane will only react with the bromine water when it is exposed to UV light. The cyclohexene will react with both bromine water

isomerization, pH values, and the importance of acids as catalysts. Imine formation begins with either an alkene or aldehyde that then produces alkenes isomers.7 Imine formation generally produces a mixture of products with E or Z conformation. This conformation is more commonly denoted as cis or trans. The trans product, or E, forms when the highest priority groups are on opposite sides of the alkene double bond, which is the more stable of the two conformations due to a lack of steric interaction wherein

distributions among the product. Theory In an elimination reaction, the reagents in question proceed in either an E1 or E2 reaction mechanism in order to produce an alkene. For this experiment, 1-butanol and 2-butanol, proceeds
