for NMR Spectrum looking at a molecule we have to decide with where the protons are in the environment how many signals will show on the NMR Spectrum. I don't understand why they are saying the protons in the pink are going to all show one signal and the protons in red are going to show their own signal. To me the line of symmetry goes down the middle of the compound and they are symmetrical so they all should...
