It would be expected that the smaller peak would be second because the ortho product, 2-bromonitrobenzene, is more polar and would thus be more attracted to the column. However, the smaller peak was first and had a retention time of 0.65 minutes, which is much less than the expected retention time of 2-bromonitrobenzene at 21.18 minutes.
