Solution
The number of signals in a 13C NMR spectrum corresponds to the number of different types of carbon environments in a molecule.
In p-dibromobenzene (1,4-dibromobenzene), there are two types of carbon environments:
- The carbon atoms attached to the bromine atoms.
- The carbon atoms not attached to the bromine atoms.
Therefore, we would expect to see two signals in the 13C NMR spectrum of p-dibromobenzene (1,4-dibromobenzene).
