Nicholas C. Beyer4-26-19CH 237-017Lab 9: Spectroscopic Identification of an Unknown CompoundIntroduction:Over the course of the semester, we have been taught how interpret Infrared (IR), HydrogenNuclear Magnetic Resonance (1H NMR) Spectroscopy, and Carbon Nuclear Magnetic Resonance(13C NMR) Spectroscopy data in order to determine the structure of various organic compounds.This lab assignment is a test of our ability to take the spectral data of an unknown compound,given its chemical formula, and figure out its structure on our own.Results:1.State the unknown number you were given. (Shown below.)2.Provide the correct structure for your unknown based on the spectroscopic dataprovided. (Shown below.)Discussion:1.Discuss important features of the IR,1H NMR, and13C NMR that led you to the structureyou propose.
hydrogens, which equals 20. However, the unknown structure only has 12 hydrogens.Subtract one for every trivalent atom (there are none) and add one for every monovalentatom (there are none). Set up the equation: (20 ref. H – 12 H)/2 = IHD of 4. Every pointof an IHD signifies the presence of either one ring or one double bond. Conveniently, abenzene ring, comprised of one ring and three double bonds, always leads to an increase
