The 1H NMR, 13C NMR, mass and IR spectra of compound with a molecular formula (C9H11NO2) are given below.
I need help identifying a compound based on the spectra. The compound contains an aromatic ring. The spectra are attached. I would appreciate an accurate description.
The 1H NMR, 13C NMR, mass and IR spectra of compound with a molecular formula (C9H11NO2) are given below. Use the given spectroscopic data to provide rational interpretation (motivation) of all the spectral data to determine the structure of this compound.
Homework Answers
- in the IR spectrum, the value around 3400 CM-1 and 1640 CM-1 indicates there is NH2 and ester group respectively.
- the odd mass indicates the odd number of nitrogen present in the given molecule.
- the 1H NMR indicates that the molecule is symmetrically substituted. there are two doublet at the aromatic region, one quartet at 4.2 ppm for -OCH2 group because of -CH3 group. and one triplet for -CH3 group because of -CH2 proton.
- 13C indicates there are 7 signals in the 13C spectrum.
- So based on the given data the unknown molecule is given above.
