Question

How will you distinguish between ketones,amides,acid anhydride and acid chloride using IR spectroscopy?

Answer 1

spectra of acid anhydrides and nitriles that allow us to use infrared ... than ketones, whereas the relatively unreactive amides absorb at lower frequencies. ... In acyl chlorides a lower intensity shoulder or peak near 1740 cm-1

Answer 2

the organic substances can be differentiated from each other by using IR spectrum  

Explanation:

• in this process different types of substances observe different wavelengths of light. For example the ketone and the amides absorb infrared radiation of light and life the the acid chloride which absorbe higher frequency of light.

• Acid anhydride usually e observe lower frequencies of light. In such a way the organic compounds can be differentiated from each other.
