effervescence-MGO-lab.mov The peculiar behaviour of PPh4Br when used as a spectator in a Negishi Cross-coupling reaction. Reagents - EtZnBr - Huo's method - 0.8 mL - 1M in DMI - 0.8 mmol Alkyl bromide - NONE LiBr - 150 mg - 1.7 mmol - 3 equiv Pd- PEPPSI-IPr - 4 mol % - 14 mg PPh4Br 1.0 mmol - 1.1 equiv - 420 mg THF distilled - 1.6 mL Procedure - In a flame dried flask charged with a stirbar, PPh4Br, LiBr (globebox), Pd and argon gas was added portion-wise THF and EtZnBr in succession with stirring. Observations - Upon addition of the THF (1st) and (EtZnBr) we see the insoluble salt, the formation of Pd black resulting in a dark brown solution. The lighter brown layer at the miniscus is the evolution of gas (perhaps ethene) immediate after the addition of EtZnBr.

A.8.4 Describe conjugation of double bonds and wavelength of absorption IB Chemistry As the number of conjugate double bonds increases less energy is absorbed in order to excite the bonds. So ethene absorbs at a smaller wavelength than butadiene. Phenolphthalein is colorless in acid (absorbs UV since no more than 3 conjugated double bonds) and is purple in base (the molecule now has 4 conjugate double bonds and delocalization around --CO2-).
CSAV Hawaii: Flame Bubbles on Kilauea Volcano Lava flows over vegetation, burning the wood, which distills volatiles such as methane, ethene, and benzene. The volatiles make their way up through the lava flow and form bubbles, which then burst, releasing the trapped gas. The gas instantly turns to flame, as it is ignited by the hot lava.

Photos are of a normal non FSC cigarette and an FSC. Under normal lighting conditions the difference is unremarkable. Both look nearly identical aside from the printed logo on the FSC. It seems as though the ink has bled or did not adhere properly to the treated paper. Under short and long wave UV light you can clearly see distinctively darker bands; one at or near the tip, one in the center and a small portion near the filter but most likely the smaller band is same length as the other bands. Usually the rolling paper is adhered inside of the filter. Natural American Spirit brand just recently began incorporating the FSC papers in their cigarettes or at least began releasing them to the public in Nevada about two and one half weeks ago. Depending on the retail store in which you purchased a pack, some were FSC and some were not. I noticed that they would go out occasionally and some would taste strange, also if ashes dropped off of the tip they would actually burn me! I have been smoking this brand loyally for many, many years and it quite irks me that this specific company continues to state that they offer an organically natural product? Maybe its just me but I think that they should either stop using the ethylene-vinyl acetate treated paper or just remove the word natural from the companys identity and marketing ...

10.3.4 Outline the Polymerisation of Alkenes IB Chemistry Alkenes behaver as monomers (simple building blocks) that can be joined together to form long chains called polymers. Ethene can make polyethene, propene can make polypropene etc. These are addition polymers - the reaction completely uses all the monomer, no extra small molecule is also produced like in condensation polymers.
