Unknown # 315-S20-2 Mol. Wt. = 181.0 g/mol C-33.17% H=5.01% 0 = 17.68% Molecular Formula Degree of Unsaturation = Mass Spectrum IR spectrum (liquid film) 100- Relative Intensity 150 175 25 50 75 100 125 m/z Based on the M.W., circle & label the molecular ion peak (M). Spectrum Region Frequency (cm ) Peak Shape (sharp, broad) MAVUTO Peak Intensity (strong, med., weak) Name of functional group Indicated Abbrev. Structure of functional group From M, does the compound contain nitrogen? Explain. >3000 cm Does the compound contain chlorine or bromine? Between 3000-2000 cm If so, circle the mass spec m/z peaks that indicate their presence. Label the peaks with the approximate intensity ratio of the isotopic molecules. Between 2000-1400 Expanded structure of compound (show all atoms, bonds, non-bonding electrons). Give the compound name. Between 1400-500
