Lab 12: “Putting Pieces Together" using IR, MS, C&'H NMR for Spectroscopic Identification of Organic Unknown Compound You have been provided t CsH6Brz. Use all Pectral dati -vided to identify the compound and hence I the spectral data of an unknown organic compound J, which has the formule in calculate the DOU and explain. clearly label and assign ALL peaks in the 'H and "C NMR spectra to relevant protons and carbons in your compound. Explain all splitting patterns in terms of the structure you have determined. Use the table shown. Recall that the number of hydrogens for cach NMR peak can be determined by comparing the integration ratios. The integration heights have been provided to you (in mm) on the spectrum. In addition, justify your compound's terms of the IR absorptions and at least two mass spectrum-fragments. show/draw the fragmentation pathy actor the formation of those mass spectrum-fragments. remember, sometimes a compound can have more than one functional group - can be identical functional groups! Note: Simply jus iving the structure is noCenough. You MUST provide a brief writen justification your decision or R2032 nemis nic Chemistry 753 IR Spectrum liquid film) 1200 800 4000 3000 2000 1600 V (cm) Organic Chemistry Mass Spectrum 100 80 121/123 60 0 803 TWITTYY % of base peak M+- 200/202/204 40 20!
