And that’s of course what we see right here. So the shift is just past two, this signal represents three protons, and it’s these three protons right here. Alright, next, let’s look at these two protons. So these two protons are next to an Oxygen, so the Oxygen deshields that. Those two protons are also next to this Benzene ring over here, so we would expect a higher chemical shift. Alright, and we have two protons and of course, it’s this signal, which corresponds to two protons. Finally, we have five nearly equivalent protons on our ring, so they might not be exactly the same, but for the signal here, right, we have five protons giving us this signal, and it’s a little more complex than the other ones, but, notice where it is. Right where– aromatic region, in terms of a chemical shift. And so this signal must represent these five aromatic protons on our ring. And so this shows you how useful the integration values are. They tell you how many protons are giving that signal, which allows you to figure out the structure of the molecule.
