    Hi, just wondering have I counted the proton environments right for this molecule? Name:  hahhaa.png
Views: 70
Size:  25.7 KBI got 5 different hydrogen environments. Attachment 580940580942 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? Name:  qqqq.png

    Are you sure that was compound K?

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

    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

    Yes.
