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 arrange 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 rig 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 constitutive(a) models a good deal in the same way as towboat chromatography. The all differences be that it uses a moving gas phase and a stationary liquid phase, and that the temperature of the gas system contribute be controlled. In a gas chromatograph the sample is shot in with a syringe and is immediately dehydrationized 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 in truth 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 molecules can b e attracted in many ways. Interactions inclu! de salt formation, coordination, total heat bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample will separate accordingly. Finally at the end where the gases come turn out is a detector which generates a signal that is recorded on a strip chart rec commit. Elimination reactions are reactions that severalise a individual(a) reactant into... If you want to get a full essay, order it on our website: OrderCustomPaper.com
