Proton NMR for aromatic compounds

Hi, just wondering have I counted the proton environments right for this molecule? hahhaa.pngI got 5 different hydrogen environments.

For the peak with area of 5, I have no clue how you can get that from the molecule. The answer says the peak is produced from the protons in the benzene ring, but I really don't see how...

Also is this right? qqqq.png
Thanks

Are you sure that was compound K?

Anyways, the environments on the ring can overlap, being very close together.

I made a mistake, I have just edited it. Thanks

So, as I said, you can reason from the integration (and the δ value) in this case, as the ring environments tend to be very close and overlap sometimes.

Oh okay but have I counted my hydrogen environments right for both molecules? Thx
