    For the compound below tell how many signals you would expect the molecule to have in its normal, broadband decoupled 13C NMR spectra

    The compound has 2 planes of symmetry. The different carbons are labeled with different letters. Three different carbons = three peaks in the C-13 ...

    Solution Summary

    The solution shows examples of equivalency and discusses the difference between diastereotopic, homotopic and enantiotopic protons.
