Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

In the book The Compound by S.A. Bodeen‚ there are multiple themes being portrayed by the book. One of the main themes in the book is even if you think you may know someone‚ you may not. Throughout the book‚ many parts of the book show this‚ and talk about trust. Many elements of the book also play off of how well people know each other. The family all trust the father about why they are going into the compound‚ that there’s enough food and supplies‚ everyone is truthful‚ fine in their well being

H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight‚ I calculated

Traditional way of synthesizing sensitive rhodamine starts with rhodamine B‚ amino compound‚ and some alkali additive in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction

Morioka Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Date Performed: April 25‚ 2013; Date Submitted: April 30‚ 2013 Alkyl halides could be synthesized through several processes and using different compounds as reactants. One of the simplest method used is the addition of a hydrogen halide to an alcohol. In this research‚ tert-butyl alcohol was reacted with cold concentrated HCl to produce tert-butyl chloride. The crude product was distilled to yield

Chilean Copper Mine Collapse Chilean Copper Mine Collapse A small copper mine in San Jose‚ located in north Chile‚ collapsed trapping workers underground. The mine collapsed on August 5th‚ trapping 33 workers in the mine. The coverage of this mine collapse came two long weeks after the traumatic event. Initially the incident did not catch any news worthy attention. Mine collapses are pretty common but the accident finally caught the interest of an editor‚ and then it went viral from

Synthesis of Chloroform -------------------------------------------------------------------------------- With Calcium Hypochlorite and Acetone When chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone

Physical properties of organic compound Low boiling point group: alkane‚ alkene‚ alkyne and ether Boiling point is the exact temperature that the state of compound change from liquid to gas‚ which need to break the intermolecular forces. The stronger the intermolecular forces‚ the higher the boiling point. Since straight chain alkane‚ alkene and alkyne only experience dispersion forces‚ the compound with more carbons have higher boiling point as more carbons contribute more forces. Branched

Identifying Organic Compounds Joe Harris 11/12/07 1. Background Organic compounds are‚ by definition‚ any chemical compound containing carbon. These compounds include carbohydrates‚ polysaccharides‚ lipids‚ proteins‚ and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the

Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration
