Once the distillate had been collected into two separate vials, both distillates were washed with aqueous sodium bicarbonate (1.5-ml, 5%). The aqueous layer (lower) was extracted from both vials using a pipette and put into a chemical waste bin. The organic (alkene) layer was then dried with anhydrous calcium chloride pellets (3 pellets per vial). Both distillates were analyzed using gas chromatography, and each peak shown was identified to be one of the alkenes. Analysis of the graph was used to determine

CH 220C – Organic Chemistry Lab Experiment 13: Electrophilic Aromatic Substitution: Nitration of Bromobenzene and Relative Rates of Reaction Rodan Devega Introduction Electrophilic aromatic substitution (EAS) reactions involve the replacement of a hydrogen atom bonded to an aromatic compound by an electrophile. The rate and direction of the EAS reaction depends on the functional groups present on the aromatic compound. The purpose of this experiment was to synthesize bromonitrobenzene by reacting

economic, emotional, physical and cultural history that makes medical care much more than just writing a prescription to fix a disease. When I began working as a physical therapy aide I had a tremendous amount to learn. My general biology and organic chemistry classes did not prepare me for the knowledge I was going to gain from this job experience. I had a lot to learn about shoulder injuries and knee replacements to be able to teach patients full exercise routines to help them heal. Fortunately

until sin had came in the way, In the creation myths, there are three main ideas; organic materials being used for creation of humans, creator or creators destroying life, and feuds among the people. In many creation myths around the world, creating humans out of organic materials is present in almost every myth. Organic materials can be man-made from organic compounds; or can form naturally in nature. Organic materials are built up overtime, and with a prolonged amount

18F-fludeoxyglucose Chemical Structure: - Formulation: - 18F-FDG is synthesized by electrophilic fluorination with 18F2. Carrier free dissolved 18F-fluoride (18F-) ions in water is produced by proton bombardment of 18O-enriched water which causes a (n-p) reaction in 18O. 18F- is then separated from the aqueous solvent by trapping it on an ion-exchange column. It is then eluted with an acetonitrile solution of 2,2,2-cryptand and potassium carbonate and evaporated to give [(crypt-222) K]+ 18F-

Nitration of Methyl Benzoate Abstract: This procedure demonstrates the nitration of methyl benzoate to prepare methyl m-nitrobenzoate. Methyl benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction, in which the nitro group replaces a proton of the aromatic ring. Following recrystallization, melting point and infrared

Introduction: For this experiment, the major goal was to see the rate of Bromination of six different hydrocarbons in order to find the relative order of each reaction. An excess of each hydrocarbon is combined with molecular bromine and then the elapsed time of color disappearance is collected both in and out of light. The results are then compared for each hydrocarbon in an attempt to figure out the fastest and slowest reactions based on the hydrogen types. Experimental Procedure The first

Thalidomide is a drug, which has the molecular formula of C13H10N2O4, it is made up of a pair of optical isomers. Optical isomers are two or more forms of a compound that have the same structure but are mirror images of each other. They have identical physical and chemical properties. They differ in how they react with different chiral molecules (a carbon attached to four different types of atoms. The isomers are extremely difficult to separate. Thalidomide was first synthesized by reaction of N-phthaloyl-glutamic

whereas that of organic material such as wood is 40 Mpa. Other organic things are easier to break. So, if we apply a stress between these two critical pressures we can break the organic matter keeping the plastic intact. The exact value should be optimised experimentally.

This will help in better biodegradation of the organic wastes as
