1H NMR: How do I figure out what molecule this is? (#2)
« on: May 01, 2018, 11:27:11 PM »
I'm stuck on #2 in this series of problems: https://imgur.com/gallery/0ihWLVu/comment/1355550715.
 It looks like it's chloroaniline, since it has aromatic peaks and the same MW, except that it doesn't have a peak at around 4 ppm.  I was thinking N-chloroaniline, but for some reason there are no H peaks on nitrogen, so I'm not entirely sure.  Am I on the right track to figuring this out?

Also, are the other molecules I drew (in the other problems) correct?

I understand your confusion, however I believe these are idealized spectra, not real ones. I think it would help if you explained how you arrived at chloroaniline, and which chloroaniline do you think fits best? And can you think why N-H protons might far off on a computer generated spectrum compared to a real data base one?
