A molecule with the molecular formula of C₃H₆O₂ produces the IR spectrum shown below. Draw a structure that best fits this data.

### IR Spectrum Analysis

The IR spectrum is a graph displaying absorbance versus wavenumber (cm⁻¹), which helps identify functional groups within the molecule. Key features within the spectrum:

- **Peak at ~3300 cm⁻¹:** This generally indicates the presence of O-H (hydroxyl) or N-H (amine) bonds.
- **Sharp peak around 1700 cm⁻¹:** Commonly associated with C=O (carbonyl) groups.
- **Multiple absorptions from 1000 to 1500 cm⁻¹:** These could relate to C-O (ether or ester) stretching or C-H bending vibrations, indicating more complex structures.

Based on the molecular formula and IR spectrum, the molecule likely contains functional groups such as alcohols, carboxylic acids, esters, or ketones. Students should utilize this information to hypothesize a suitable molecular structure.
