Ive got 4 spectra and have to identify which are salicylic acid and asprin.
Firstly am I right in saying that both salicylic acid and asprin have 6 H+ environments?
Presuming I am, only 1 of the 4 spectra has 6 peaks :/
Theres 1 with 6 peaks, 1 with 5 and the other 2 have 4 so I'm confused :/
Any advice? Or have I missed something?
Thanks
Yes, they both have six environments.
It's possible that the COOH proton does not show up in the acid as it's very labile and may give a very broad (and hence, flat) peak. If you are doing the NMR with a D2O shake it won't show at all.

Thanks I went to see a lecturer about it and she said if theres any water in the sample then the COOH proton might not show up (something like that)
