Two bottles labelled cis-cyclohexandiol were found in a laboratory. Because of their differing melting points, the bottles clearly contained two different cis-cyclohexandiol isomers. To determine which isomer was in which bottle, the chemist decided to run ¹3C NMR spectra on a sample of each. The three possible products were as in the figure. (Figure 1) The two ¹³C NMR proton-decoupled spectra contained the following data: ● ● Figure HO spectrum of sample in bottle A: 20.20, 62.55 spectrum of sample in bottle B: 16.09, 29.52, 36.15, 63.08 OH OH OH 1 of 1 OH OH Part A Identify which isomer was present in the bottle A.
