Question

please label the IR spectrum

Answer 1

Answer #1

3400 cm-1, very weak, N-H stretch in amide

3058 cm-1, medium-weak, aromatic sp2 =C-H stretch

2736 - 2969 cm-1, medium peaks, sp3 alkyl C-H stretch

1678 cm-1, strong, amide C=O stretch

1594 cm-1, strong, amide N-H bending

1400 - 1600 cm-1, medium-weak, multiple bands due to aromatic sp2 C=C stretch

1350 - 1480 cm-1, medium paeks, sp3 alkyl C-H bending

Conclusion: It looks like the compound is most probably N-methyl benzamide.

N-Methylbenzamide INFRARED SPECTRUM 1 0.9 0.8 0.7 1000 4000 3000 2000 Wavenumber (cm-1) Relative Transmittance
