Question

i need a little assistance with finding the chemical name of this nmr

pPM 100 PPM

Answer 1

Answer #1

Tiny Peak at around 11 ppm indicate probably COOH group. This can also ascertained by peak 170 ppm in c13 nmr

there are lot so overlapping peak in 7-8 ppm in 1H nmr and 120-130 ppm in c13 nmr both confirms the presence of aromatic ring benzene

finally there is singlet at around 2-3 ppm which is due to Me attached with benzene which causes deshielding of Me

so the probable structure will be

p-methyl benzzoic acid

COOH 4-methylbenzoic acid

Select the reason why chemical shifts are expressed in units of ppm in NMR spectroscopy. The chemical shift of a nucleus is highly dependent on its chemical environment in a molecule. The frequency of a chemical shift is strongly correlated to the concentration of the sample, in units of ppm. The frequency of a chemical shift is strongly dependent on the solvent used. The frequency of a chemical shift is dependent on the operating frequency of the instrument.
