I am trying to learn how to interpret 1H-NMR for the two above spectrums. How would you interpret these 1H-NMR spectrums to determine the shape of the molecule whose formula is C13H9NO3?
Homework Answers
Formula of the compound is C13H9NO3.
Double bond equivalence = C + 1 - H/2 + N/2 = 13 +1 - 9/2 + 1/2 = 10
Stucture of the compound is:
Analysis of 1H NMR:
2Ha ; doublet; 8.35 ppm
2Hb; doublet; 7.95 ppm
2 Hc; doublet; 7.8 ppm
1He; triplet; 7.65 ppm
2 Hd; triplet; 7.50 ppm
