**Title:** Analyzing the IR Spectrum for C₄H₆ **Introduction:** A molecule with the molecular formula C₄H₆ produces the IR spectrum shown below. Draw a structure that best fits this data. **IR Spectrum Explanation:** The IR spectrum displays the transmittance of infrared radiation by the molecule, plotted against wavenumbers ranging from 4000 cm⁻¹ to 500 cm⁻¹. Notable peaks in the spectrum can indicate the presence of specific functional groups within the molecule. **Diagram Analysis:** - The spectrum shows several key peaks: - A sharp peak around 3300 cm⁻¹ - Multiple smaller peaks between 2100 cm⁻¹ and 1500 cm⁻¹ - Additional peaks in the fingerprint region below 1500 cm⁻¹ **Task:** Based on the IR spectrum provided, use your understanding of IR spectroscopy to determine the structure of a molecule that fits the molecular formula C₄H₆. Consider the presence of alkene or alkyne functional groups as potential contributors to the observed peaks. **Interactive Section:** - Use the interactive drawing tool below to sketch your proposed structure. - Consider the identified functional groups and spectral data in your design. **Select to Draw:** [Interactive Drawing Box] --- **Conclusion:** Once you've drawn a structure, compare it with known structural possibilities for C₄H₆ and verify if the functional groups align with the peaks observed in the IR spectrum.
