**Determine the Structure of a Compound with a Molecular Formula of C₆H₁₂O**

### NMR Spectra Analysis

**¹H NMR Spectrum:**

- **Chemical Shifts (ppm):** The spectrum shows multiple peaks across various regions:
  - A set of peaks around 1.0-1.1 ppm with an integration value of 6.
  - A set of peaks around 0.9-1.0 ppm with an integration value of 3.
  - Another set of peaks around 2.4-2.6 ppm with an integration value of 2.
  - Peaks around 2.5-2.6 ppm with an integration value of 1.

- **Peak Details:**
  - The ¹H NMR signals suggest different sets of chemically non-equivalent hydrogen atoms within the molecule.
  - The integration values indicate the relative number of protons represented by each set of peaks.

**¹³C NMR Spectrum:**

- **Chemical Shifts (ppm):** Features distinct signals across a broad range:
  - Peaks are primarily located in the region between approximately 10 and 80 ppm.
  
- **Peak Analysis:**
  - The ¹³C NMR spectra helps in identifying the variety of carbon environments within the molecule.
  
**Additional Notes:**

- **No Peaks Exchange in D₂O:** This suggests the absence of protons capable of exchanging with deuterium, indicating that there are probably no -OH or -NH groups.

Understanding these NMR spectra is essential for deducing the molecular structure of C₆H₁₂O, allowing us to infer how atoms are arranged and determine functional groups present in the compound.
