Once recovered‚ the solids were purified by recrystallization and examined by thin-layer chromatography‚ and their identities were derived by melting point and infrared (IR) spectroscopy. Extraction is a procedure that selectively dissolves one or more of the mixture compounds into a proper solvent. Extraction refers to the moving of compounds from one liquid solvent to another liquid solvent. A compound can be disconnected from impurities in

that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic compound Covalent: nonmetal & nonmetal

However for compound B the mean melting point is close to both Compound 1 and Compound 4 so IR spectra are needed to correctly determine the structure of B. By comparing the IR spectrum for Compound B it can see that it is 1-(4nitrophenyl)ethanoate‚ this is indicated by the peak at 763.16cm-1 when compared against literature values for IR Spectroscopy

analysis of organic compounds determine the elements present in them but they do not give the actual structure or the functional groups present. Since all organic compounds contain hydrogen and carbon‚ most tests consist of only the determination of oxygen‚ sulfur‚ nitrogen and halogens – elements that are most of the time the only ones involved in organic compounds. The experiment focused on the Sodium Fusion test‚ which tested for all elements except oxygen. In the test‚ the test compound is broken down
