Question
**Mass Spectrum of Iodoethane**

This mass spectrum graph provides an analysis of iodoethane. 

- **Title:** Ethane, iodo- MASS SPECTRUM

- **Axes:**
  - The x-axis represents the mass-to-charge ratio (m/z), ranging from 0 to 160.
  - The y-axis shows the relative intensity, with a maximum value of 100. 

- **Key Features:**
  - A significant peak appears near m/z = 155, indicating the molecular ion peak of iodoethane.
  - Another prominent group of peaks is observed around m/z = 20-50, likely representing fragment ions.
  - A notable, smaller peak is also visible around m/z = 127, commonly attributed to the iodine atom.

This spectrum is useful for identifying the molecular structure and composition of iodoethane, demonstrating the fragmentation pattern typical for halogenated hydrocarbons. The high intensity at m/z = 155 points to the presence of the complete molecule before fragmentation.
