Question
The image shows an infrared (IR) spectrum graph with the following details: **Title:** Which of the following structures is consistent with the IR spectra shown below? **Graph Explanation:** - **X-Axis:** - Labeled as "Wavenumbers (cm⁻¹)" and ranges from 4000 to 500 cm⁻¹. The wavenumbers are marked at intervals of 500 cm⁻¹. - **Y-Axis:** - Labeled as "% Transmittance" and ranges from 0% to 100%. It is marked in intervals of 20%. - **Graph Pattern:** - The spectrum exhibits peaks and troughs characteristic of specific molecular vibrations. - Notably, there are absorptions that could correspond to certain functional groups. **Structures Displayed:** - The bottom left corner displays various molecular structures as possible answers for the corresponding IR spectrum. These include: 1. A molecule with a phenyl ring and a carbonyl group attached. 2. A branched alkane. 3. A benzene ring with a substituent labeled Y. 4. A cyclohexane ring. **Options to Proceed:** - Two buttons are available at the bottom for saving and submitting answers: "Save All Answers" and "Save and Submit." This content could serve as an exercise in determining the correct molecular structure based on IR spectral analysis on an educational platform.
