Identification of anLab ReportUnknown by SpectroscopyPurposeThe purpose of this experiment was to identify an unknown compound through asolubility test as well as through instrumentation such as IR spectroscopy, massspectrometry, and NMR spectroscopy.Results1.My unknown compound G was soluble in all of the organic solvents it was testedwith through the solubility test; it was soluble in ether, benzene, CH2Cl2, EtOH,and EtOAc. My unknown was insoluble when mixed with cold water, it wasinsoluble when mixed with 5% hydrochloric acid, and it was also insoluble whenmixed with sodium hydroxide. This indicates that my functional group may havean aromatic, a hydrocarbon, a halide, an alcohol, an aldehyde, a ketone, an amide,an ester, and/or an unsaturated hydrocarbon.2.The IR spectrum is attached to my lab report. In terms of just my IR spectrumalone, the only functional group that I saw based on this data was a carbonylgroup, which was not listed in part 1.3.The1H NMR spectrum is attached to my lab report. As stated in the worksheetattached (number 16), the ketone functional group and the aromatic ring appearedin my spectrum, and these were both listed in part 1 (cpp.edu). No, there were nofunctional group that I found on this NMR spectrum that was not listed in part 1.Discussion1.Figure 1: This figure shows the structure of my unknown, which I have identifiedto be acetophenone.
