Lab report on E2 substitution on alkyl halides.

Alkenes by Elimination Kyle Peterson Chem. 243a Matt Judd, Sec. 25 Date Per bodyed: 11/12/03 Abstract: The objective of this experiment is to successfully make away a dehydration of a 2-butanol and a dehydrohalogenation of 2-bromobutane to form the products 1-butene, trans-2-butene, and cis-2-butene. It was make that a dehydration of 2-butanol yielded 4.6% 1-butene, 67.3% trans-2-butene, and 28.1% cis-2-butene, and a dehydrohalogenation of 2-bromobutane yielded 19.1% 1-butene, 69.9% trans-2-butene, and 11.0% cis-2-butene. Backround: Gas Chromatography calves positive specimens ofttimes in the same way as chromatography column chromatography. The simply differences be that it uses a moving gas phase and a stationary liquid phase, and that the temperature of the gas system place be controlled. In a gas chromatograph the sample is shot in with a syringe and is immediately vapourized in a heated injection chamber. It is then introduced to a moving be adrift o f gas called the carrier gas which sweeps the vaporized sample into a column filled with particles filled with liquid adsorbent. This column is ordinarily filled with liquid that has a low vapor jam and high boiling and is called the stationary phase. This phase is in addition ordinarily coated onto a support material very equally and packed into a tubing apparatus as horizontally as possible and placed in the temperature controlled oven. When organic solutions are passed through the tubing van der Waals forces attract the nonionic molecules peculiarly if they have large molecular weights. Polar molecules can be attracted in many ways. Interactions include salt formation, coordination, enthalpy bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample get out separate accordingly. Finally at the end where the gases come out is a detector which generates a signal that is recorded on a strip chart rec cast. Elimination reactions are re actions that set off a individual(a) react! ant into... If you want to get a full essay, order it on our website: OrderCustomPaper.com
