sketch a 1H-NMR and a 13C-NMR for vanillic alcohol and label each peak.
Which peak would NOT be in either the decoupled 13C or 1H NMR spectra of the molecule shown below? a)a singlet around 65 ppm (13C) b)a quartet around 2. 1 ppm (1M) c)a doublet around 1. 1 ppm (1H) d)a singlet around 170 ppm (13C) e) a singlet around 220 ppm (13C) f) a singlet around 3. 5 ppm (1H) 2) For which pair of molecules below would decoupled l3C NMR spectroscopy not be effective in easily telling apart?
Label relevant peaks on both the 1H NMR and 13C NMR of 1,4-dimethoxy-2,5-di-tert-pentylbenzene
1. Provide the 1H and 13C NMR data for 4-ethyl-1-cyclohexanecarboxaldehye Report the 1H NMR data in the sequence: chemical shift, integration, multiplicity (e.g. 1.0, 3H, triplet). Be sure to clearly label which proton and carbon you are reporting. 2. Provide the 1H and 13C NMR data for ethylene glycol. Report the 1H NMR data in the sequence: chemical shift, integration, multiplicity (e.g. d 1.0, 3H, triplet). Be sure to clearly label which proton and carbon you are reporting.
