Transcribed Image Text:**Title: Analyzing Molecular Ion Patterns in High-Resolution EI Mass Spectrometry**
**Text:**
Which of the following compounds generated the molecular ion pattern shown below in the high-resolution EI mass spectrum? HINT: There are two different peaks at m/z ~200.
**Compounds:**
- **A:** Contains a bromine (Br) and a chlorine (Cl) atom.
- **B:** Contains two bromine (Br) atoms.
- **C:** Contains two chlorine (Cl) atoms.
**Graph Description:**
The graph is a mass spectrum, illustrating the intensity (on the Y-axis) and the mass-to-charge ratio (m/z, on the X-axis).
**Key Features of the Spectrum:**
- **Significant Peaks:** Notable peaks are observed at approximately 197.98109 and 199.97904 m/z.
- **Additional Peaks:** Smaller peaks appear at intervals around 199.97814 and 201.97609 m/z.
- **Range:** The spectrum ranges from about 195 to 207 m/z.
These observations suggest the presence of isotopic patterns typical of halogenated compounds. Understanding these peaks helps identify the compound responsible based on isotopic distribution.
