Elimination Conclusion: Drew Rasmussen November 7 th , 2011 The purpose of this experiment was to create an alkoxide base from sodium and an assigned alcohol for a reaction with 2-bromoheptane to form 3 different isomers of heptene for analysis. Sodium metal was cut and weighed for reaction with isopropyl alcohol. This reaction could be seen taking place due to the bubbling of the solution. When the bubbling had stopped, the reaction was finished. Once the sodium had reacted 2-bromoheptane was added to the flask and refluxed. After the reflux period a mixture of pentane and water was added to the flask, and the contents were transferred to a new tube for layer removal. The organic layer was isolated using water to extract the byproducts that would not be analyzed. What was left were the isomers trans-2-heptene, cis-2-heptene, and 1-heptene, all in various amounts which would require GC/MS analysis. For Isopropyl alcohol cis-2-heptene was the most prominent isomer at about 37.13%
