    Muhammed Sabah Comparing Reactivity Of Alkanes and Alkenes Aim: To compare the reactivity of an alkane and an alkene Hypothesis: The cyclohexene would react to the bromine water and turn colourless‚ whilst the cyclohexane won’t react. Risk Assessment: What’s the problem? | How do you fix? | How does it work? | Bromine water is corrosive to the skin | Wear gloves | Stops the Bromine water from reaching skin | Cyclohexane/ene is highly flammable | Keep away from naked flames. | No naked

    Jacobsen’s Method of Epoxidation of an Alkene | | Abstract Various types of reactions were completed to first create and then use Jacobsen’s catalyst in the asymmetric epoxidation of an unknown alkene with bleach in the laboratory. The chiral epoxide synthesized was then characterized with GC/MS and NMR. With this information the unknown alkene was able to be identified as 4-chlorostyrene. Introduction Organisms have evolved with mechanisms that use specific enantiomers of molecules

    Hydrocinnamic acid underwent bromination using N-bromosuccinimide and AIBN. As one lab partner set up the reflux apparatus‚ the other measured the chemicals used in the lab experiment. 2.10 g of hydrocinnamic acid was used. It was observed as white and had a slight cinnamon smell. The amount of NBS was 2.49g and was measured in the fume hood. AIBN was measured at .030 g. 10 mL of acetic acid was also obtained. The reflux apparatus consisted of a 25 mL flask with a stir bar in a water bath. The chemicals

    The purpose of the experiment was to perform an electrophilic addition reaction by the bromination of cinnamic acid. The product of this reaction is 3-Phenyl-2‚3-dibromo propionic acid‚ which is purified by recrystallization. Cinnamic acid (3-phenylprop-2-enoic acid) is an unsaturated carboxylic acid. The electron rich π cloud (see Figure 1) in the double bond of this structure is nucleophilic and can be considered a Lewis base. It can therefore be saturated by the addition of a halogen to the double

    The Synthesis of Alkenes: The Dehydration of Cyclohexanol Adam Ohnmacht CHEM 0330 Scott Caplan 10/30/12 Abstract: In Organic Chemistry‚ many different methods are used to synthesize organic compounds from various components. In this lab‚ cyclohexanol was dehydrated to cyclohexene through an elimination reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used.

    Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be
