COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid. The

I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

Mrs. Feeney Biology 9 October 16‚ 2012 Identifying Organic Compounds Objective: To use indicators to test for the presence of organic compounds in certain substances. Theory: Major types of organic compounds in some common foods are Lipids‚ Carbohydrates‚ and Proteins. An indicator is a chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests. The purpose of using distilled water as one of the substances in the test

Identification of Unknown Organic Compound by Melting Point (M.P)‚ Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in

VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile organic chemical”

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

Experiment 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

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

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

decantation‚ extraction‚ sublimation techniques. Brief Introduction This experiment was set to teach research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is based upon the fact that each component has different physical properties. The components of mixtures are always pure substances‚ either compounds or elements‚
