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.

ABSTRACT: The Rf values of seven known color dyes and three unknown samples were observed in order to compare results and discover the hidden identities of the three samples. Three solvents‚ H2O‚ Isopropyl alcohol‚ and a 2% NaCl solution‚ were introduced to the dotted chromatography strips to show three different ratios for each dye on account of polarities. We found that all of the Unknown samples contained more than one pigment‚ sample one yielded Red #3 and Blue
