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...
