Question
What is the structure of C7H14O2 given the information. Also, what would happen if the structure were to change?

Transcribed Image Text:The image contains two nuclear magnetic resonance (NMR) spectra, specifically a ^1H NMR spectrum and a ^13C NMR spectrum.
### ^1H NMR Spectrum
- **X-axis (PPM):** Chemical shift in parts per million (PPM).
- **Y-axis (Signal Intensity):** Relative intensity of the signals.
- **Peaks:**
- **At ~12 PPM:** A singlet peak corresponding to 1 hydrogen (1H).
- **At ~4.6 PPM:** A triplet peak corresponding to 2 hydrogens (2H).
- **At ~1.2 PPM:** A triplet peak corresponding to 2 hydrogens (2H).
- **At ~0.9 PPM:** A singlet peak corresponding to 9 hydrogens (9H).
### ^13C NMR Spectrum
- **X-axis (PPM):** Chemical shift in parts per million (PPM).
- **Y-axis (Signal Intensity):** Relative intensity of the signals.
- **Peaks:**
- A single peak near 180 PPM.
- Multiple peaks between 40 and 20 PPM.
These spectra are used to identify chemical environments of hydrogen and carbon atoms within a molecule, allowing determination of the molecular structure.
