V-3. (4 pts) In H-NMR spectra, the integration of the area under a signal a. indicates the number of protons causing that signa. b. indicates the number of neighboring protons which the proton causing that signal has. c. indicates the number of protons attached to the carbon atom causing that signal. d. is meaningless because 1°C atoms are too rare to give integration data.
Determine the structure of C8H8O2 using H-NMR, C-NMR, and IR Spectrum and each signal assigned to H's in the structure. Determine the structure of C8H8O2 for the H-NMR, C-NMR, and IR Spectrum For each spectrum, the complete structure of the unknown is to be determined, and each signal assigned to H's in the structure. These are to be written on the printout of each spectrum. Formula: C8H8O2 H NMR C NMR 2Hd 2H, 12 11 10 6 5 4 3...
