Algae Could Solve World’s Fuel Crisis Von Philip Bethge Dan Robertson is working on algae that can produce biofuel. Genetically modified blue and green algae could be the answer to the world’s fuel problems. Bioengineers have already developed algae that produce ethanol‚ oil and even diesel -- and the only things the organisms need are sunlight‚ CO2 and seawater.

trans-Cinnamic Acid Pitak Chuawong Objectives 1. To perform bromination of trans-‐cinnamic acid 2. To investigate stereochemistry of bromination reaction Introduction Alkenes undergo electrophilic addition to give alkyl halides. When bromine is used as a reagent‚ the reaction proceeds via 2-‐step process. The first

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

absorption frequencies in the spectrum‚ and associate each with a specific bond (e.g. O–H‚ C=O). Keep in mind that there are usually only one or two key bands in each spectrum‚ although in some cases you might observe up to three. Do not label the alkane C–H stretch‚ since these bands are present in most organic compounds. 2. Assign a letter from the structures given (A – J). There is only one structure per spectrum. 3. Identify the main functional group present in the structure (i.e. ketone‚ alcohol

classes namely: Saturated hydrocarbons and unsaturated hydrocarbons. Saturated hydrocarbons are the simplest type of organic compounds. They are hydrocarbons in which all carbon- carbon bonds are single bonds. An example of a saturated hydrocarbon is an alkane. Unsaturated hydrocarbons are hydrocarbons that contain one or more carbon-carbon multiple bonds like double bonds‚ triple bonds‚ or both. Saturated and Unsaturated hydrocarbons have similar physical properties‚ but their chemical properties are different

PPV‚ which is the abbreviated term for phenylenevinylene‚ has light emitting properties since it has a large conjugated system. This organic molecule is possible to be formed from dichloro-para-xylene which then reacts with methanol and thiolane. The nucleophile would be the thiolane. A good leaving group in this case would be chlorine. After thiolane attacks‚ it results with dithiolane-xylene. The second step is reaction with sodium hydroxide. The hydroxide it used for deprotonation upon the substituted

Marta Gebregziabher Discussion and Conclusion: Addition reaction of Alkenes: Bromination of (E)-Stilbene 1. Addition reaction is a reaction that involved two molecules that combine to make a larger product. Addition reaction has two main types‚ electrophilic addition and nucleophilic addition. An electrophilic reaction is when the pi bond of a molecule is removed to make two covalent bonds that are bonded to two new molecules. A nucleophillic addition is a reaction that removed the pi bond
