The proton NMR has three peaks; a singlet at 2.2 (3H), and a singlet at 10 (1H) and two doublets centered around 7.6. The doublets centered at 7.6 are in the aromatic region; the fact that two doublets are observed (2H each) suggests a 1,4-disubstituted aromatic compound.
The peak at 2.2 is in the region for a methyl group adjacent a mildly electronegative group. The singlet at 10 is in…
