Based on the given IR spectrum peaks, the unknown organic compound likely contains the following functional groups:1. A broad peak at 3400 cm-1 indicates the presence of an O-H group, which could be from an alcohol or a carboxylic acid.2. A sharp peak at 1700 cm-1 suggests the presence of a C=O carbonyl group, which could be from an aldehyde, ketone, carboxylic acid, or ester.Considering both peaks together, the most probable identity of the unknown organic compound is a carboxylic acid, as it contains both the O-H and C=O functional groups. However, further analysis, such as NMR spectroscopy, would be necessary to confirm the exact structure and identity of the compound.
