    The 2 Hs on Cs adjacent to the C attached to the Br are more deshielded so are further downfield. So those 2 Hs shouls show s triplet further down. The other 2 Hs on the ring father from the C with Br should show a triplet a bit more upfield from the previous triplet. Finally the 3 Hs on the CH3 show 1 peak way upfield.

    Main point: the 4 Hs on the ring are not equivalent. The closer to an electronegative element, the more deshielded the h will be.

    Hope this answers your questions.

      Not exactly. Heh. How can "those 2 Hs shouls show s triplet further down"when one doesn't even have any vicinal hydrogens and the other has only one(should be a doublet)? Er. It should be a triplet, a doublet, and 3 singlets.
