WebA1) It turns out that a simple 1 H-NMR spectrum is not particularly useful; it cannot be used to assign protons in a straightforward manner. The spectrum below was obtained from a student sample and demonstrates the difficulty of assigning spectra for this compound. Only the 9 H-atoms in the tert-butyl group are readily discernible. WebCyclohexanol consists of alcoholic group along with the hydrocarbon ring structure. By employing IR spectroscopy over the cyclohexanol molecule, determination of alcoholic group and carbon–carbon bond is done.
