Pleaseeeee
2. Explain how you would use 'HNMR and IR to distinguish between each of the following pairs: In other words, what difference(s) would you expect in (a) the IR spectra of the two compounds and (b) what difference(s) would you expect in the NMR spectra of the two compounds. (15 points). DO NOT INCLUDE INFO THAT IS COMMON FOR BOTH (a) A IR for B IR for A NMR for A NMR for B
