Identification of Unknown Organic Compounds by MP BP and Infrared Spectroscopy Zeba N. Keti Berberi September 11 2014 Methods and Backgrounds. The purpose behind this.
In trying to find organic compounds within everyday foods four tests were conducted over the course of two days with multiple food items. Indicators were essential in the process of pinpointing exactly what kind of organic compounds were presents. Test were conducted to find Lipids Simple Sugars Proteins and Starches.
To test several different foods of unknown composition to determine what organic compounds they contain. Test tubes Test tube racks Glucose solution Starch solution Protein solution Fat or oil Iodine Benedicts solution Biuret solution Brown paper Hot water bath Vitamin C solution Indophenol NaCl solution Silver nitrate a variety of foods. Organic compound Test using bromine water Test using acidified potassium dichromate solution Test using magnesium ribbon.
If the compound is organic a solvent that will dissolve it can usually be found. If a compound is found to dissolve in water the pH of the aqueous solution should be estimated with pH paper or litmus. Compounds soluble in water are usually soluble in all the aqueous solvents.
If a compound is only slightly soluble in water it may be more. Organic Compounds Lab Analysis Names. Test for Complex Carbohydrates using iodine test tube Substance Color Before Color After Starch - 1 Starch 2 Glucose 3 Sucrose 4 gelatin 5 water Table 2.

You will learn chemical tests that will allow you to distinguish one functional group from another. You will use the chemical tests to identify the functionality of an unknown organic compound. In addition you will use a water solubility test to determine whether your organic compound is of high or low formula weight.

Four classes of organic compoundscarbohydrates lipids proteins and nucleic acidsare found in large amounts in living organisms. PART A WEEK 1 - SOLUBILITY TESTS Organic compounds follow three interdependent rules of solubility. Small organic molecules are more soluble in water than are large organic molecules.
Polar organic molecules especially those capable of hydrogen bonding are more soluble in water than are nonpolar molecules. Substances called indicators can be used to test for the presence of organic compounds. An indicator is a substance that changes color in the presence of a particular compound.
In this investigation you will use several indicators to test for the presence of lipids carbohydrates and proteins in various foods. ISO 18562-3 Biocompatibility Evaluation of Breathing Gas Pathways in Healthcare Applications - Part 3. Tests for Emissions of Volatile Organic Compounds states that all gas pathways from which a patient inspires gas shall be evaluated for VOC emissions subject to a risk management process.
Testing if required is performed at a time after. Properties of Alkanes Alkenes and Alkynes B. Physical Properties When a compound burns in the presence of oxygen the reaction is called a combustion.
Like most organic substances hydrocarbons are combustible. The general reaction is given below. Organic Compound O 2 g.
CO 2 g H 2 Og HeatEnergy 1. Organic compounds containing C C and or C C bonds are called unsaturated compounds. These compounds undergo addition reaction with bromine water or the solution of bromine in carbon tetrachloride chloroform or glacial acetic acid.
Addition of bromine to an alkene results in the formation of vicinal dibromide. RNA are all organic compounds which are studied in biochemistry. Complex organic compounds are present in the foods we eat carbohydrates proteins fats etc Most medicines whether they come from a chemical plant or a green plant are organic compounds.
