#### Molecular Formula
- **MF:** C₆H₁₂O₂
#### NMR Spectrum Interpretation
###### 1H NMR Spectrum
The provided NMR spectrum displays signals that represent different hydrogen environments in the molecule. The x-axis represents the chemical shift in parts per million (PPM).
- **Peak at ~4.0 PPM:** This peak is designated as 3H, indicating 3 hydrogen atoms contributing to this signal.
- **Peak at ~2.5 PPM:** Labeled as 1H, suggesting that 1 hydrogen atom is present in this chemical environment.
- **Peak at ~2.0 PPM:** This peak has 2H, associated with 2 hydrogen atoms.
- **Peak at ~1.0 PPM:** Labeled as 6H, indicating 6 hydrogens are present.
The relative intensities of these peaks provide insights into the symmetry and chemical environment within the molecule.

**C. Compound: C₆H₁₂O₂**
### Infrared (IR) Spectrum:
- The IR spectrum displays various peaks indicating different functional groups present in the molecule. The specific absorption bands should be analyzed to deduce functional groups like alcohols, carbonyls, etc.
### Carbon-13 Nuclear Magnetic Resonance (¹³C NMR) Spectrum:
- The ¹³C NMR spectrum shows peaks at specific ppm values, indicating the chemical environment of the carbon atoms in the compound. The peaks' positions help identify different types of carbon atoms (e.g., alkane, alkene, carbonyl).
### Proton Nuclear Magnetic Resonance (¹H NMR) Spectrum:
- The scan is incomplete here, but would typically provide information about the hydrogen atoms' environment in the molecule, including signal multiplicity indicating neighboring hydrogen interactions.
**Graph Analyses:**
1. **IR Spectrum:**
- The graph shows transmittance against wave numbers (cm⁻¹). The dips in the spectrum represent absorption peaks. Key peaks should be correlated with common functional groups.
2. **¹³C NMR Spectrum:**
- The graph displays chemical shift values from 0 to 200 ppm. Peaks represent the different carbon environments in the molecule. The number of distinct peaks indicates the number of unique carbon environments.
By analyzing these spectra, you can propose a possible structure for the compound C₆H₁₂O₂. Consider the functional groups suggested by the IR spectrum and the carbon environment given by the ¹³C NMR data.
Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.
