Question

Short answer

Since the replacement of each by X atoms forms two diastereomers, the \(C{H_3}\) groups are not equivalent to those attached to the third carbon.. Thus, every C in this compound is different, and there are five 13-C signals.

Step-by-step solution

13C-NMR

The 13C-NMR splitting pattern reflects how many protons are directly attached to the carbon atom.The 13C-NMR helps to distinguish between \(CH, C{H_2}, C{H_3}\)groups.
