WEBA precise analysis of the 'H nmr spectrum of toluene as a dilute solution in carbon disulfide yields a revised set of spectral parameters. The chemical shift of the para proton lies 12.6 ppb to low frequency of that of the ortho protons at 300 K.
organic chemistry - What is number of 1H NMR signals for toluene ...
WEBMay 4, 2018 · I am searching the web for the number of 1H NMR signals of toluene and I find two different results. Some say there are two signals while others say there are four (According to me, it should be 4). For the two signals, it suggests that all five aromatic hydrogens are taken as equivalent.

6.6 ¹H NMR Spectra and Interpretation (Part I)
WEBAs seen in the 1 H NMR spectrum of methyl acetate (Fig. 6.6a), the x-axis units of the NMR spectrum are in ppm (not in H z, as we would expect for frequency), and the two signals stand at different positions along the x-axis. Let’s explain how that works and what information can be obtained.
