Homework Answers
You are absolutely right for both.
Peaks at 3248 &3403 cm-1 For NH2 stretch and 3060 for sp2 CH stretch and at 1662 for C=O stretch (conjugate to benzene ring) and at 1619 for C=C , aromatic ring.
Peak at 780 for para disubstituted Benzene ring
And peaks at 615-751 for Ortho disubstituted Benzene ring.
And at 1356& 1566 for symmetrical & asymmetrical stretch of NO2 in 2nd molecule.
