Synthesis and Chemistry of Alkenes - Essays.
This experiment used 4-methyl-2-pentanol with excess acetic acid to produce (1,3-dimethylbutyl) acetate as seen in Figure 1. The mixture of acetic acid with 4-methyl-2-pentanol and sulfuric acid was refluxed, extracted, distilled and identified using IR spectroscopy. The ester had a fruity smell when obtained.
The product of the dehydration of 4-methyl-2-pentanol was then analyzed using gas chromatography (GC). The large peak at 2.30 minutes is the solvent (diethyl ether) used to prepare the sample and the starting alcohol in my product appeared at about 4.17 minutes.
The alcohols 1-propanol and 2-pentanol were converted into alkyl halides through a certain series of steps. The first step was reflux, and the purpose of reflux is to add energy to the solution and not lose any solution to evaporation. This energy helps initiate the acid-catalyzed dehydration reaction and also promotes rearrangement.
Abstract The objective of this experiment is to successfully perform a dehydration of 1-butanol and 2-butanol, also dehydrobromination of 1-bromobutane and 2-bromobutane to form the alkene products 1-butene, trans-2-butene, and cis-2-butene. The dehydration reactions react under and acid-catalysis which follows an E1 mechanism.
Following are examples of compounds listed by functional group, which demonstrate patterns which can be seen in mass spectra of compounds ionized by electron impact ionization. These examples do not provide information about the fragmentation mechanisms that cause these patterns. Additional information can be found in mass spectrometry.

Synthesis of an Alkyl Halide Essay .ASynthesis of an alkyl. This lab will examine the reaction of 1-propanol and 2-pentanol with NaBr in H2SO4, in which the H2O acts as the leaving group and Br as the attaching nucleophile (1). After the reaction has taken place through reflux and distillation, the product is able to be examined through.
