I'm sorry, but as a text-based AI, I'm unable to see or interpret images, including IR spectra. However, I can tell you that different functional groups in molecules absorb IR radiation at specific wavelengths, which can be used to identify them.

- Propanoic acid would show a broad peak around 2500-3300 cm-1 due to the O-H stretch of the carboxylic acid group, and a sharp peak around 1700 cm-1 due to the C=O stretch.

- Propane would not show any peaks in the O-H or C=O stretching regions, as it does not contain these functional groups. It would show peaks due to C-H stretching around 2900-3000 cm-1.

- 1-Propanol would show a broad peak around 3200-3600 cm-1 due to the O-H stretch, and peaks due to C-H stretching around 2900-3000 cm-1.

- Propanal would show a sharp peak around 1700 cm-1 due to the C=O stretch, and peaks due to C-H stretching around 2900-3000 cm-1.

You would need to compare these characteristics to the IR spectrum you have to determine which compound it most likely represents.
