Good question! 13C-NMR is based on the unique chemical environments of the molecule's carbon atoms, and we follow the same guidelines when determining which environments are unique (symmetry, rotation, etc.). That means this molecule has four unique carbons: from left to right, C1, C2, C3, and C4 (the ketone-carbon). Every other carbon in the molecule falls within one of these same chemical environments. So, you should see four peaks in 13C-NMR.04/16/20
