Question

WHich of these molecules best corresponds to IR spectrum shown. and why

**Question:** Which of these molecules best corresponds to the IR spectrum below with molecular formula \(C_6H_{14}O\)? **Molecular Structures:** - a) - b) - c) - d) - e) **IR Spectrum:** - **X-axis:** Wavenumber (cm\(^{-1}\)) ranging from approximately 500 to 3500 cm\(^{-1}\). - **Y-axis:** Transmittance, ranging from 0.0 to 1.0. **Key Features of the Spectrum:** - A broad peak around 3300 cm\(^{-1}\), indicative of an O-H stretch, suggesting the presence of an alcohol group. - Peaks in the region of 2800-3000 cm\(^{-1}\), typically associated with C-H stretches from alkanes. - A series of smaller peaks between 1000-1500 cm\(^{-1}\), possibly indicating O-H bending or C-O stretching. **Conclusion:** The IR spectrum corresponds to a molecule with an O-H group present, likely fitting the molecular formula \(C_6H_{14}O\). Based on spectral analysis, the molecule that matches this IR spectrum is most likely structured with an alcohol group, which would typically result in the broad O-H stretch observed.
