ochem* proton NMR What would you look for in the NMR spectrum of benzoic acid that would confirm its presence?
Based on the following IR and NMR is this benzoic acid,
2-methoxybenzoic acid or o-toluic acid? And why
Acid IR
assign the major absorptions in the IR spectra, assign chemical
shifts in both NMR, designate the parent peak in the mass spectra
data and assign the major fragments to their corresponding peaks,
and finally provide the structure for the formula.

Please assign structural labels for the following NMR reading.
Given the expected result was 4-vinylbenzoic acid, identify the
structural elements and the impurities shown in the NMR. Also show
the J-coulling values for the produced.
