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 transact 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 strand 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 constituent(a) prototypes a good deal in the same way as tower chromatography. The merely differences be that it uses a moving gas phase and a stationary liquid phase, and that the temperature of the gas system butt joint be controlled. In a gas chromatograph the sample is shot in with a syringe and is immediately vaporisationized in a heated injection chamber. It is then introduced to a moving be ad rift 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 in addition ordinarily coated onto a support material really 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 nonionised molecules peculiarly if they have large molecular weights. Polar mo lecules can be attracted in many ways. Inter! actions include salt formation, coordination, atomic number 1 bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample testament separate accordingly. Finally at the end where the gases come proscribed is a detector which generates a signal that is recorded on a strip chart rec guild. Elimination reactions are reactions that break open a individual(a) reactant into... If you want to get a full essay, order it on our website: OrderCustomPaper.com
