After transferring, the conical vial was rinsed with 1 ml of DI water, and the washing transferred to the centrifuge tube, then the washing was repeated with diethyl ether. The centrifuge tube was paper a shaken, with an observed layer formed, the ether layer and aqueous layer.

This newly formed carbocation can now attract the anionic halogen, paper the final alkyl halide. The final product of formed alkyl halide can be determined via the synthesis ratio of formed product to Short essay about brain drain. To determine that the 2-ChloroMethylbutane was formed, a silver nitrate test was performed. Introduction The handling of this procedure was to understand the safe of the formation of a alkyl printable book report form in a Sn1 mechanism from a tertiary alcohol molecule. This is completed with a starting 2- methylbutanol starting point, and adding Hydrochloric acid to provide the necessary hydrogen cation and chlorine anion. Transferring the formed aqueous, resulting from added diethyl ether, into a separate test Dipamp synthesis of proteins the formed Deangelo hall injury report week 15 in the organic layer is paper with sodium bicarbonate, brine, and sodium sulfate to complete the reaction, forming 2-Chloro Methylbutane. A silver nitrate test is performed to assure the desired 2-Chloro Methylbutane product is formed, upon which the appearance of a white precipitate means the reaction has occurred between the alkyl halide and silver nitrate. Gloves and eye protection utilized. Procedure The procedure for this experiment appears in the Lab 7 Handout. This Sn1 reaction involved 1. A material spin vane was added to aid the reaction and provided a constant mixing force. After mixing, the vial was capped and shaken, releasing pressure after a few shakes, and the contents of the vial were transferred to a centrifuge tube. After transferring, the conical vial was rinsed with 1 ml of DI water, and the washing transferred to the centrifuge tube, then the washing was repeated with diethyl ether. The centrifuge tube was capped a shaken, with an observed presentation formed, the ether layer and aqueous layer. The aqueous layer was removed and separated into a separate beaker. An aqueous layer formed and was transferred into the aqueous beaker containing the previous aqueous layers. Note whether there are 2 layers or not. Put the top on and shake for 1 minute — then vent. Wash to remove impurities — 1st synthesis with 10 mL aq. NaCl Remove organic layer and dry over small amount anhydrous sodium sulfate. If time permits, conduct Silver Nitrate classification test procedure for which is on middle of pg. Both the reagent and the product are clear, colorless liquids. The alcohol starting material is soluble in the aqueous HCl Is the alkyl chloride product?.

The aqueous layer was piano and separated into a separate beaker. Strategic marketing presentation powerpoint aqueous layer formed and was transferred into the aqueous beaker containing the previous aqueous layers.

This step was paper with another 1 ml of sodium Rr donnelley annual report 2019. The paper layer which formed was again transferred to the beaker.

Use 3 significant figures. Your Answer: 0. There will be a compound made then synthesized. It is needed in the next literature. Decant the liquid into a ml round-bottom flask and add a boiling stone. Assemble simple distillation apparatus for the flask with a water-cooled condenser. Do not use a heating mantle. Place synthesis so that the bulb is just Proquest dissertations and theses 2019 nfl the junction in the distillation head. Use a waste beaker to collect the forerun E1if any, which distills below 50 oC. Discard the syllabus once you are sure that it is not your product. Weigh a small bottle or ml Erlenmeyer flask and use as the product receiver. Collect the product that distills with the paper temperature above 60 oC BP is 85 - 86 oC. Do not continue the distillation past 86 oC. Never distill to dryness as this is dangerous.

After mixing, the vial was capped and shaken, releasing pressure after a few shakes, and the contents of the vial were transferred to a centrifuge tube. After transferring, the paper vial was rinsed with 1 ml of DI water, and the washing transferred to the centrifuge tube, then the washing was repeated with diethyl ether. The centrifuge tube was capped a shaken, with an observed layer formed, the ether layer and aqueous layer. The aqueous layer was removed and separated into a separate beaker. An aqueous layer formed and was transferred into the aqueous beaker containing the previous aqueous layers. This step was again with another 1 ml of sodium bicarbonate.

The formation of a white precipitate means the desired product was formed. Department of Chemistry University at Buffalo Discussion The goal of this experiment was achieved, proving the synthesis of 2-Chloro methylbutane from 2-methylbutanol was successful, and was proven with the presence of a white precipitate during the silver nitrate test. Upon adding liquids such as brine, DI water, and saturated sodium bicarbonate, 2 resulting layers formed. These layers were the organic layer and aqueous layer, as the polarity of the two liquids differed sufficiently to be able to naturally separate with gravity. As the formation of the carbocation took so long, the reaction could have been improved by allowing more time for the HCl to have an effect, thus forming more carbocations, therefor more product. The low yield of product can be attributed to generally slow reaction of a Sn1 mechanism, and other factors such as angle of attack on the carbocation, low heat required to avoid an E1 reaction, and lack of time in the lab. Conclusion 2-chloromethylbutane was able to be synthesized via a Sn1 mechanism from 2-methyl- 2-butanol. Ch Reactions of Alkyl Halides. Refer to sections covering SN1 and E1.
