Question

Which region in the IR spectrum could be used to distinguish between butanoic acid and 2-butanone? 1680-1750 cm-1 3200-3600 cm-1 2500-3300 cm-1 1600 cm-1

Answer 1

2500-3300 cm-1

Step-by-step explanation:

Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. This can be analyzed in three ways by measuring absorption, emission and reflection. The main use of this technique is in organic and inorganic chemistry.

They record how much of the infrared light makes it through the compound. Some frequencies will pass through completely unabsorbed, whilst others will experience significant absorption as a result of the particular chemical bonds in the molecules.

Answer 2

2500-3300 cm-1

Step-by-step explanation:

The correct answer is;

2500-3300 cm-1

This was obtained by comparing the spectra data of both compounds.
