What is the Structure of the Unknown Compound Based on NMR and IR Spectroscopy?

Click For Summary
SUMMARY

The discussion focuses on identifying the structure of an unknown compound using NMR and IR spectroscopy. Key findings indicate the presence of nitrogen, an amide group, a carboxylic acid group, and an aromatic ring. The molecular weight is determined to be 138, with a melting point between 124 and 134 °C. The user expresses confusion over the NMR peaks and seeks assistance in drawing the compound's structure.

Homework Statement



I have attached the IR and NMR spectrum from lab. I have determined that there was a nitrogen present in the compound. There was no sulfur or halogens. The molecular weight was 138. The compound was solid and yellow color. It had a melting point between 124 and 134 C.


Homework Equations



I have read 2 chapters on NMR and IR, but the compound is so confusing. It has peaks everywhere. I would appreciate any kind of help.


The Attempt at a Solution



After looking at various websites and books, I think I have an amide group, a carboxyl acid group and aromatic ring. I have no clue if that's even right and how on Earth I am going to draw the structure of compound. What does the UV stand for?

Appreciate any kind of help. I have spent weeks on this and its due Monday. Thanks.
