Number of signals: Indicate the number of signals expected in each region. 0-50 ppm 50-100 ppm 100-150 ppm 150-220 ppm

These three isomers are difficult to distinguish using 1H NMR, but are readily identified using 13C NMR. Which of the following observations is correct in identifying an isomer of xylene using 13C NMR? o In the proton-decoupled 13C NMR spectra o-xylene will display 3 peaks. O In the proton-decoupled 13C NMR spectra m-xylene will display 4 peaks.

Assign which atoms in the adduct give which chemical shifts in the 1H and 13C NMR, the spectra are provided in your lab manual. (The singlet at 7.26ppm in the 1H NMR and the triplet at 77.00ppm in the 13CNMR are due to solvent.)1HNMR(CDCl3) :131 NMR (CDCl3):1H NMR of mixed pinacolone-piperonaldehyde adduct Solvent =CDCl3(7.26ppm), Bruker 300MHz ...
