Solution:
The given IR spectrum belongs to an ester.
Explanation:
There is a strong peak near 1700 cm-1 which confirms the presence of carbonyl group.
Thus, compound will be either ester or carboxylic acid
The broad peak at 3500 cm-1 is absent, which confirms that the OH group is absent. Thus, compound can not be an carboxylic acid because it contains an O-H group.

Please evaluate the IR spectrum. Provide a structure and note
any important peaks corresponding to the structure.
It was an experiment using:
isoamyl alcohol + acetic acid
sulfuric acid as the catalyst
and the products are isoamyl acetate and water. Thank you so
much!!!
