Each of four compounds shown has one signal in the aromatic region and one signal in the alkyl region of its H NMR spectrum. Use the integral values to determine which compound's H NMR spectrum is shown below. Choose the correct molecule choice at the bottom and explain how you arrived at your answer (explain how you eliminated the other possible answers) Note: peaks at 7.26 ppm, 1.55 ppm, and 0.00 ppm are from the NMR solvent water and TMS they aren't from the compound
