Final answer:
There would be 14 signals appearing in the 13C NMR spectrum, as each listed chemical shift value represents a unique carbon environment in the molecule.
Step-by-step explanation:
The student has asked about the number of signals expected in a 13C NMR spectrum. The given data lists several chemical shift values in ppm, which correspond to unique carbon environments in a molecule observed during 13C NMR spectroscopy. The chemical shift values provided are 22.4, 24.2, 62.1, 65.0, 66.2, 69.9, 78.9, 79.2, 98.4, 128.6, 129.0, 129.6, 133.6, 165.3. Each of these values represents a distinct signal in the 13C NMR spectrum, indicating that there are 14 unique carbon environments, and therefore, there would be 14 signals appearing in the 13C NMR spectrum.
