Question:

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

pPM 100 PPM

pPM 100 PPM

Answers

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
