Problem- Considering the 13C NMR spectras for o-nitrophenol and p-nitrophenol. Please label each peak in decreasing order of ppm value and give a thorough explanation on why it is given such valuee compared to the other peaks. In your explanation made for each one of the peaks, make sure you relate to resonnance forms of the molecules. Thank you.
Please illustrate work if possible thanks
