Phenyl group in proton NMR - Chemistry Stack Exchange
Suppose you have this spectrum and the molecular formula of $\ce{C10H12O}$ The structure is . My problem is with the peak at ~7 which is an H-Benzene signal, with quartet splitting and a relative area of 4. Surely this means that: The benzene would have only one Hydrogen environment ; with 4 Hydrogens in that environment
