    NMR spectra of 3,3,5-trimethyl-cyclohexanol

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Obtain a 1H NMR spectra of the product in CDCl3 (given with this posting). Integrate the two low-field sets of peaks at 3.8 and 4.2 ppm, analyze the coupling constant (J) patterns to assign the two sets of peaks (as I discussed before, the MNova software auto assigns it for you), and report the percentage distribution of cis- and trans-3,3,5-trimethyl- cyclohexanol formed in this reaction, from the area under these C-H peaks.

    I integrated the entire spectra for NMR, I don't know how to assign the coupling constant in mastering nova and have no idea how to solve the percent distribution at all

    I have filled in the CG calculations, would you please double check for accuracy?
