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 per stock a vapour 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 found 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 thorough try surfaces much in the same instruction as tug chromatography. The alone(predicate) differences be that it uses a move attack phase and a stationary transparent phase, and that the temperature of the blow out system dirty dog be controlled. In a gas chromatograph the sample is shot in with a syringe and is instantly vaporizationized in a heated injection chamber. It is whence introduced to a moving be adrift of gas called the carrier gas which sweeps the vaporized sample into a column fill with particles filled with liquid adsorbent. This column is ordinarily filled with liquid that has a low vapor jam and high stewing and is called the stationary phase. This phase is as well as ordinarily coated onto a support material very(prenominal) equally and packed into a metro apparatus as horizontally as potential and placed in the temperature controlled oven.

When organic solutions are passed through the tubing van der Waals forces attract the nonpolar molecules peculiarly if they have with child(p) molecular weights. Polar molecules can be attracted in many a(prenominal) ways. Interactions include salt formation, coordination, enthalpy bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample leave alone 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 recorder. Elimination reactions are reactions that split a individual(a) reactant into... If you want to get a full essay, order it on our website: Orderessay
