You have been provided ine spectral data of an unknown organic compound L, which has the formula CsH6N2. Use all the spectral data provided to identify the compound and hence - calculate the DOU and explain. clearly label and assign ALL peaks in the 'H and 3C 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 each NMR peak can be determined by comparing the integration ratios. The integration heignts have been provided to you (in mm) on the spectrum In addition, justify your compound's structure in terms of the IR absorptions and at least two mass spectrum-fragments. show/draw the fragmentation pathway Tor the formation of those mass spectrum-fragments. remember, sometimes a compound can have more than one functional group - can be different or identical functional groups! Note: Simply just giving the structure is not enough. You MUST provid a brief written justification for your decision. 2268 IR Spectrum (liquid film) 4000 3000 2000 1600 1200 800 Icm 100 Mass Spectrum 66 29 80F 60 % of base peak 40 M+ = 94 (<1%) 20 C5H6N2 40 80 200 240 280 120 160 m/e Page 1 of 2
