ABSTRACT
In order to differentiate the organic compounds. The group tested the compounds using the information based on their instinsic physical properties, behavior in ignition,acidity and basicity and their infrared spectra. The physical properties were noted by the reaserchers by the means of their physical state,color and odor.Using the following reagents: H2o, 5% NaOH solution and 5% HCl solution. Solubility and miscibility were tested. Acidity and Basicity of the compounds were determined by the use of litmus paper. Ignition test was conducted using 3 to 5 drops of the sample in a small evaporating dish and light with a match. Lastly, the infrared spectrum was use to classify organic compounds according to their functional groups.

INTRODUCTION

Organic compounds are the complex compounds of carbon. Because carbon atoms bond to one another easily, the basis of most organic compounds is comprised of carbon chains that vary in length and shape. Carbon atoms have four valence electrons that make them bond with each other easily. Thus organic compounds are classified according to their carbon chains that vary in length and shape. Hydrogen, nitrogen, and oxygen are the most common atoms that are generally attached to the carbon atoms.
Organic compounds can be classified as hydrocarbons and hydrocarbon derivatives on the basis of their hydrogen replacements by other elements or by other group of elements (functional group).All hydrocarbons are insoluble in water because of their relatively non-polarity and easily distribute. When hydrocarbons burn using oxygen, C02 and H20 are the sole products. There are 2 large classes of Hydrocarbon namely: unsaturated and saturated hydrocarbons.Unsaturated hydrocarbons contains one or more carbon-carbon

    In this laboratory assignment, the spectroscopy data and molecular formula were given for 3 unknowns. An effort was made to conclusively identify these unknown samples using only the spectroscopy data, specifically 1H-NMR, 13C-NMR, and IR spectroscopy. Although mass spectrometry was given for the samples as well, its use was suggested only for confirmation, not identification, of the unknowns. Mass spectrometry was not included in the identification analysis of the compounds, however was used for confirmation of unknown #46. The spectroscopic data was analyzed using standard techniques, and the identity of the unknown samples were…

    By Using specific methods of compounds detection, we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment, identifications of the unknown ketone was accomplished using thin layer chromatography, melting point, and NMR spectrometry. Thin layer chromatography is very quick but sensitive way of determining the components of a mixture or a specific compound from a list of knowns. This method is the one which was utilized in the following experiment. When comparing a sample of known compounds with an unknown’s Rf values and appearance on the thin layer chromatograph these characteristics can be used to easily determine which known the unknown is. The Rf values are important in determining the more polar molecules from each other, while the color and appearance can be used to separate compounds with similar polarities. The color added by the reaction with 2,4-dinitrophneylhydrazine eliminates the need to compare colors of the different knowns with the unknown. The other method used to help determine which ketone the unknown was, was nuclear magnetic resonance spectrometry or NMR. NMR utilizes radio frequency waves to determine the number of carbons present and what they are connected to. With this information and the type of hydrogen present from the NMR, an accurate estimate of the unknown ketone can be made.…

    The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances, it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive, or independent of amount. Both chemical properties and physical properties are intensive properties used in determining the identity of an unknown (Maserton, p. 15).…

    The simplest organic compounds are hydrocarbons. Hydrocarbons contain only two elements, hydrogen and carbon. A saturated hydrocarbon or alkane is a hydrocarbon in which all of the carbon-carbon bonds are single bonds. Each carbon atom forms four bonds and each hydrogen forms a single bond to a carbon. The bonding around each carbon atom is tetrahedral, so all bond angles are 109.5°. As a result, the carbon atoms in higher alkanes are arranged in zig-zag rather than linear…
