Well the peak at 3060 seems too high to be an alkane C-H so I'm thinking there's possibly an aromatic ring?
Also I am wondering if the peak at 1,295 could be a nitro group since they are usually anywhere from 1290 - 1360? That may also explain the positive flame test/ unsaturation. I am quite inexperienced with nitro groups in organic compounds so is it reasonable to think that it could also be responsible for the smell and yellow color of the solution as well?
Am I misreading it entirely and the peak at 3400 is actually an amine?
Also, the peak at 1592 is too low to be a carbonyl right?
