Answer 2

Answer:

The amide functional group combines the features of amines and ketones because it has both the N-H bond and the C=O bond. Therefore amides show a very strong, somewhat broad band at the left end of the spectrum, in the range between 3100 and 3500 cm-1 for the N-H stretch.

The infrared absorption spectrum of any organic molecule

is as distinctive and unique as a fingerprint. Since the

observed set of absorption bands are, in essence, a display

of some of the resonant vibrational frequencies of the molecule, the infrared spectrum is directly related to molecular

parameters such as bond lengths and angles, bond groups

("functional groups") and molecular symmetry. Thus, an

infrared spectrum not only provides information on the

identity of "unknown" compounds, but also yields definite

data on its molecular structure.
