In examining the IR spectrum, I noted that there were peaks for CH2-x where x is bromine, methylene (2 peaks) and a peak corresponding to a methyl group; I concluded that I've synthesized n-bromobutane. Is the method I used to interpret my spectra sound? *CDCl3 was the IR solvent In addition, in looking at the HNMR spectra, I concluded that the protons shown in the NMR spectra corresponded to the groups determined in the IR spectra. My only concern is that the approximate ppm(s) seem to be shifted yet I know that this may not necessarily mean that my interpretation is wrong. Can someone confirm that my logic is sound and supported? I've attached the NMR and the IR. http://i42.photobucket.com/albums/e309/Alex_Jsoh/IRSpectrum-page-001_zps084bb818.jpg http://i42.photobucket.com/albums/e309/Alex_Jsoh/NMRSpectrum-page-001_zpsdd2a7edc.jpg Thanks!
