    Hi guys,


    So in my orgo class we only went over nmr basics and didn't deal with symmetry much. In this topscore question no. 78 A is the right answer and I see the 4 nonequivalent protons(after symmetry is taken into account). But I count 2 singlets and 2 doublets but no triplets. Where do they get the triplet from because i don't think there are any CH2 protons on xylene?

    The hydrogen on carbon on the far left is split by two equivalent hydrogens, one on each side.
