Decide on a structure which is consistent with the spectral data, and 'assign" both spectra as best as you can. "Assign" = draw structure, label (a,b,c etc) and indicate which peaks belong to which type.
- A'2 The 'H-NMR spectra of cyclohexanol and cyclohexanone are given below. Identify which spectrum belongs to which compound and assign the peaks in each spectrum that substantiate your decision.How do I interpret, label, and determine which molecule this H NMR graph represents? The three molecule choices are methylene cyclohexane, 3-methylcyclohexene, or 1-methylcyclohexene.I need help interpreting these 3 spectra, h-nmr,c-nmr, IR. All three correlate to same molecular structure. The question asks you to determine the molecular structure and label all peaks on all 3 spectra.
