91T Q9) Identify the unknown aromatic compound using the following spectra. Use the ‘H NMR splitting in the aromatic region to determine the substitution pattern on the aromatic ring. Label and assign all relevant peaks on the IR and NMR spectra. For the Mass Spectrum, label the molecular ion peak, base peak, and any halogen isotopes, along with any mass losses (change in m/z between peaks) that are helpful in determining your structure. ortho meta arbitrary units 140 160 180 200 220 240 Tonice n toomrenin ANUGERI i
