## Question 8**Task:** Select the functional group present in the molecule with the formula C\[_7\]H\[_12\]O and identify the functional group using the provided IR spectrum.### IR Spectrum Analysis- **Graph Overview:** - The graph represents an Infrared (IR) spectrum with the x-axis labeled "Wavenumber (cm⁻¹)" ranging from 4000 to 500. - The y-axis is labeled "Transmittance (%)" ranging from 0 to 100%.- **Key Features of the Spectrum:** - **Peaks:** - There is a significant peak around 1700 cm⁻¹, which is characteristic of the C=O (carbonyl) stretch often seen in aldehydes, ketones, or carboxylic acids. - Broad peaks around 3000 cm⁻¹, which could indicate C-H stretching from alkanes or the presence of other functional groups like alcohols. - Other peaks at lower wavenumbers may represent various bending vibrations or other functional group stretches.### Data Table| Wavenumber (cm⁻¹) | Peak Intensity (%) ||------------------|--------------------|| 2932 | 4 || 2908 | 1 || 2856 | 8 || 2805 | 3 || 2705 | 2 || 1727 | 5 || 1461 | 17 || 1395 | 64 || 1362 | 66 || 1329 | 72 || 1286 | 64 || 1233 | 70 || 1204 | 71 || 1170 | 70 || 1143 | 70 || 1098 | 58 || 1056 | 66 || 1024 | 78 || 1003 | 72 || 968 | 97 || 927 | 81 || 881 | 55 || 943 | 67 || 915 | 52 || 888 | 66 ||
