Comparative Investigation of Organic Compounds

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 samples also underwent a test using litmus paper to classify its acidity, basicity or neutrality. The next procedure was the ignition test, which classified the sample as to whether the sample was flammable, or non-flammable and the color of the flame were noted. After going through all the tests, it was proven that organic compounds possess different properties.


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. Hydrogen, nitrogen, and oxygen atoms are the most common atoms that are generally attached to the carbon atoms. Each carbon atom has 4 as its valence number which increases the complexity of the compounds that are formed. Since carbon atoms are able to create double and triple bonds with other atoms, it further also raises the likelihood for variation in the molecular make-up of organic compounds. [1] Carbon can also bond with itself and hydrogen to form both chains and rings called hydrocarbons. Because the covalent bond between carbon and hydrogen is nonpolar, these carbon skeletons are hydrophobic. Functional groups can be added to carbon skeletons to make them more hydrophilic. Differences in the carbon skeleton and attached functional groups cause organic molecules to have different chemical properties. The chemical properties of a molecule determine how it interacts with other...
