Background This experiment was performed to determine the identity of an unknown organic liquid using physical constants: physical state, color, and odor, the solubility classification: water soluble or insoluble, the results of characterization tests: Lucas test, 2,4-Dinitrophenylhydrazine test, Bromine in Methylene Chloride test, and Ferric hydroxamate test, and analyses of spectral data: IR spectrum and HNMR . All testing samples were added to testing tubes for observation. Data was collected to discover the boiling point of the liquid. The data collected through these methods was then used to determine the name and the structure of the unknown organic compound.

N-Butyl is also known as n-Butanol, or Butanol, it is a primary alcohol with a 4-carbon structure and the chemical formula C4H9OH. (N-Butanol, 2017) “N-Butanol occurs naturally as a minor product of the fermentation of sugars and other carbohydrates, and is present in many foods and beverages. (N-Butanol, 2017)” It has a boiling point of 117 degrees Celsius, a density of 0.81 g/cm3, soluble in ethanol and water. The odor can be alcoholic and harsh. (N-Butanol, 2017) Compared to my calculation I was only off by one point for the boiling temperature. As far as the classification test my accuracy remained constant, my results from the Lucas test indicated I had a primary alcohol given there was no change occurring when I added the Lucas reagent. For my IR spectrum, I have confirmed C-H stretches at absorption levels of 1,370, 970, and 985. An O-H absorption occurred around the 3,000-3040 vibration making indications that there was an alcohol present. My NMR gave triplet and singlet multiplicity occurring from approximately 1.0-3.5 ppm. Those data points are in correct correlation with the indications of
