Analyze the peaks in this NMR spectrum of p-nitrophenol assigning the peaks, discuss multiplicity, splitting, shielding/deshielding effects, and integration. I have assigned the peaks but i am not sure if i have done it correctly. Is there expected to a peak for the -OH? or is there not a peak because the proton is exchangeable? is there complex or normal splitting observed? 901 C 18 1.00 19 -429 -7.5 7030 P-nitrophenol OH H NMR, nitrophenol in CDCl un A 7...

Assign the NMR peaks below DIRECTLY onto the paper, please!!!! The impurities are water at 2.19 ppm and acetone at 1.6 ppm. So just ignore those peaks. The peaks for the aromatic Hydrogens can be grouped up to one (I believe they are the left most peaks at around 7 to 7.5 ppm. Given that please assign the rest of the hydrogens.
