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 serve 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 erect 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 entire auditions ofttimes in the same way as editorial chromatography. The wholly differences be that it uses a moving gas phase and a stationary liquid phase, and that the temperature of the gas system drive start 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 of 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 alike ordinarily coated onto a support material rattling 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 nonionized molecules peculiarly if they have large molecular weights. Polar molecules can be attract ed in many ways. Interactions include salt f! ormation, coordination, total heat bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample pass on 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 smart set. Elimination reactions are reactions that severalize a individual(a) reactant into... If you want to get a full essay, order it on our website: OrderCustomPaper.com
