Interpretation of IR spectrum
The given IR spectrum shows the following peaks,
3410 cm-1 peak for N-H stretch
3049 cm-1 and 3016 cm-1 peaks for sp2 =C-H stretch
2850-2950 cm-1 all peaks for aliphatic C-H stretch
1600 cm-1 for C=C stretch
1504 cm-1 for aromatic C=C stretch
746 cm-1 for monosubstituted benzene
Possible structure for the compound could be,
phenyl ring-aliphatic chain-NH2
examples : 2-phenylethylamine, N-methyl-benzylamine, and like compounds
