**Exploring Unique Carbons in NMR Spectroscopy**

The concept of unique carbons in a molecule is crucial for interpreting the \(^{13}C\) NMR spectrum. Each unique carbon atom in a structure corresponds to a distinct signal in this spectrum. 

**Task:**

Identify the number of unique carbons in the given molecular structure.

**Molecular Structure:**

- The structure shown is a benzene ring with two bromine (Br) atoms attached to it.
- The bromines are positioned parallel to each other across the benzene ring, resulting in a symmetrical configuration.

**Instructions:**

Using the interactive calculator provided on the right side, determine the number of unique carbon environments in this structure. 

The molecular symmetry suggests fewer unique carbon environments, as atoms in symmetric positions can generate identical chemical shifts in the NMR spectrum.

**Interactive Calculator:**

- Input the number of unique carbon environments you identify in the structure.
- Use the numerical keypad for input and the clear or backspace buttons (\(\times\), \(C\)) to correct any mistakes.

This exercise helps in understanding how molecular symmetry affects NMR spectroscopy, simplifying the interpretation of complex molecular spectra.
