Peaks of the 4 H appear at:
Ha - 7.30ppm
Hb- 6.95 ppm
Hc- 7.26ppm
Hd- 7.38ppm
Ha appears at 7.30 ppm whereas Hc appears at 7.26 ppm because Ha is closer to the nitro group which is a electron withdrawing group and deshields the proton to a greater extent. So, Ha has a higher chemical shift than Hc. Hb splits as a triplet of doublet. Hc splits as a triplet.Hd splits as a triplet and Ha splits as a triplet of doublet.

Introduction One of the best ways to make aromatic amines is to exploit a rearrangement reaction that breaks a C-C bond. To achieve the rearrangement, you need to make an acyl nitrene intermediate (or suitable derivative). There are a variety of these processes: the Curtius and Schmidt rearrangements access the nitrenes from acyl azides, but these can be explosive, so aren't ideal for an undergraduate lab. The other method is to...
