Hi I am a bit confused would like some help. First attachment is just an example, the actual problem I would like help for is C9H11Cl # NMR Spectrum Analysis GuideTo analyze each problem effectively, you must complete the following steps:1. **Calculate the Degree of Unsaturation:** - Determine the number of unsaturated bonds or rings in the compound.2. **Assign the Principal IR Absorption Bands Above 1500 cm⁻¹:** - Identify the functional groups present within the compound based on IR spectroscopy.3. **Draw the Structure of the Compound:** - Sketch the molecular structure accurately.4. **Label the Protons on Your Structure with Letters and Assign Them to Peaks on the NMR Spectrum:** - Use letters to label different hydrogen environments in the molecule. - Correlate these labels with corresponding peaks observed in the NMR spectrum.### Example:The given diagram features an example of a chemical compound and its corresponding NMR spectrum.#### NMR Spectrum Explanation:- **Peak A (1.0 ppm, 3H):** - This peak corresponds to the protons labeled "A" on the compound structure. - The area under this peak indicates 3 protons (3H), suggesting they are likely part of a methyl group.- **Peak B (1.5 ppm, 2H):** - Protons labeled "B" correlate with this peak. - With two protons (2H), this peak may represent a CH₂ group adjacent to other groups affecting its chemical shift.- **Peak C (3.5 ppm, 2H):** - Peak "C" is linked to two protons (2H), indicating a different environment from peak B, often corresponding to a -CH₂- group near an electronegative atom like oxygen.- **Peak D (2.5 ppm, 1H):** - The proton labeled "D" matches this peak. - As it represents a single proton (1H), it may be near a functional group impacting its shift differently from other hydrogens.### Molecule Structure:The structure provided in the diagram includes labels for protons (A, B, C, D) on different parts of the chemical structure:- **A (3H)**: Possibly a methyl group.- **B (2H)**: Likely a methylene group.- **C (2H)**: Another methylene group.- **D (1H)**: Hydrogen attached to a specific functional group or part of the ### Chemical Analysis of Compound: C9H11Cl#### Infrared (IR) Spectrum AnalysisThe graph on the top represents the IR spectrum of the compound C9H11Cl. The x-axis represents the wavenumber in cm⁻¹, ranging from 4000 cm⁻¹ to 600 cm⁻¹. The y-axis represents the transmittance percentage.Key absorption peaks are observed at the following wavenumbers:- **3084.35 cm⁻¹** and **3062.73 cm⁻¹**: These peaks typically indicate the presence of C-H stretching vibrations in an aromatic ring.- **2968.61 cm⁻¹** and **2927.25 cm⁻¹**: These peaks correspond to aliphatic C-H stretching vibrations.- **1601.45 cm⁻¹**: This peak is characteristic of C=C stretching vibrations in an aromatic system.- **1251.37 cm⁻¹**: This peak likely represents C-Cl stretching.- **822.12 cm⁻¹** and **684.22 cm⁻¹**: These peaks often indicate C-H out-of-plane bending in aromatic compounds.- **745.82 cm⁻¹** and **700.25 cm⁻¹**: Usually associated with aromatic ring vibrations.#### Nuclear Magnetic Resonance (NMR) Spectrum AnalysisThe bottom part of the image shows the NMR spectrum of the compound. The x-axis represents the chemical shift (δ) in parts per million (PPM), while the y-axis represents the signal intensity.Key signals (peaks) are observed at the following chemical shifts:- **7.5 to 6.5 PPM**: A multiplet peak corresponding to the aromatic protons (designated as 5H).- **3.3 to 3.4 PPM**: A doublet peak corresponding to 2 protons (2H).- **3.0 to 3.2 PPM**: Another doublet peak corresponding to 2 protons (2H).- **2.2 to 2.3 PPM**: A triplet peak indicating 2 protons (2H).By analyzing these spectra, we can infer the presence of aromatic rings, aliphatic groups
