Below are the ¹H NMR spectrum of triphenylmethanol, benzophenone, and bromobenzene. Identify the compound corresponding to each ¹H NMR spectrum and draw the structure next to the ¹H NMR spectrum. Assign ALL peaks in each of the three ¹H NMR spectra. Hint: Conjugated systems (benzophenone) including an electronegative atom will cause a more downfield shift of ring protons in ¹H NMR compared with non-conjugated systems (bromobenzene). 8 8 8 7 7 7 6 6 6 5 5 5 4 PPM 4 PPM 4 PPM 3 3 3 2 2 2 1 1 0 0
