Rework Problem 37 as it pertains to ¹³C NMR spectroscopy.

Rework Problem 37

For each compound in each of the following groups of isomers, indicate the number of signals in the ¹H NMR spectrum, the approximate chemical shift of each signal, and the integration ratios for the signals. Ignore spin – spin splitting. Indicate whether all the isomers in each group can be distinguished from one another by these three pieces of information alone.
