Sorry to ask this in the middle of application season but I need help
on proposing a structure for C8H8O2

I have the following:
3H at 2 ppm
2H at 7 ppm
2H at 8 ppm
1H at 13 ppm

I think the structure is this

but I am not fully sure.

Any help would be appreciated. PM if you can help

4-MethylBenzoic Acid

I agree with this, checked it in a NMR database and it matches from what I can tell. It may be worth mentioning that I found it under the synonymous name "p-toluic acid".

Here's the handiest site ever for NMR: http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi
Also has mass spec and carbon NMR in addition to H NMR.

I love NMR so much, it was great fun determining unknown compounds in Ochem.
