Question
Label the major peaks in each spectrum and propose a structure for the compound.
 
This image contains an infrared (IR) spectrum graph. 

**Graph Description:**

- **Axes:**
  - The x-axis is labeled "Wavenumber (cm⁻¹)" and ranges from 1000 to 3000 cm⁻¹. 
  - The y-axis ranges from 0.0 to 0.8, presumably representing transmittance or absorbance levels.

- **Graph Details:**
  - The spectrum shows various peaks at different wavenumbers. 
  - Major absorption bands are visible, indicating different functional groups.

- **Additional Information:**
  - Text on the image indicates a molecular mass of 86, suggesting this is data related to a specific compound.

**Interpretation:**

Spectroscopy is a technique used to identify the molecular structure based on absorption of light at different wavelengths. Peaks in the spectrum correspond to the vibrational modes of bonds within the molecule. The position and intensity of these peaks help in identifying functional groups present in the sample.

The image shows an infrared (IR) spectrum graph, which is used to identify compounds and analyze molecular structures. Here is a detailed description of the graph:

- **Title/Label**: Mass = 86
- **Axes**:
  - The x-axis is labeled "Wavenumber (cm⁻¹)" and it ranges from about 4000 to 0 cm⁻¹. The wavenumber indicates the frequency of the IR radiation and is inversely proportional to the wavelength.
  - The y-axis is labeled with values ranging from -0.2 to 1.0, which likely represents transmittance or absorbance.

- **Graph Features**:
  - The graph displays a series of peaks and valleys, which indicate the absorbance of infrared light at specific wavenumbers. Each peak corresponds to a specific bond vibration within the molecule.
  - Notable regions include broad absorption bands which may reflect characteristic functional groups.

- **Notable Observations**:
  - At high wavenumbers (around 3000 cm⁻¹), you see broad, rounded peaks which could indicate C-H stretching in hydrocarbons.
  - The mid-region (2000-1000 cm⁻¹) shows more complex patterns, which could include C=O or C=C stretches.
  - Lower wavenumbers (under 1000 cm⁻¹) often reflect fingerprint regions that are unique to specific molecular structures.

This spectrum likely corresponds to a compound with a molecular mass of 86. By analyzing the specific peaks, chemists can deduce the functional groups present within the compound.
