Transcribed Image Text:**Mass Spectrometry Analysis: Compound Identification**
---
**The compound that gave this mass spectrum probably contains:**
- a) nitrogen
- b) bromine
- c) chlorine
- d) sulfur
**Explanation of the Graph**
The graph presented is a mass spectrum, which is a plot showing the relative intensity of detected ions as a function of their mass-to-charge ratio (m/z). The x-axis represents the m/z values, ranging from 10 to 120. The y-axis represents the relative intensity of the detected ions, scaled from 0 to 100.
**Key Features of the Mass Spectrum:**
- **Prominent Peaks:**
- A prominent peak with high relative intensity is observed at an m/z value of approximately 79 and a slightly smaller, closely spaced peak at approximately 81. This is indicative of bromine isotopes (^79Br and ^81Br) as the peaks are approximately in a 1:1 ratio, characteristic of bromine.
- Other peaks are observed at lower m/z values, specifically around m/z = 20-30, which are likely due to fragmentation patterns of the molecule containing bromine.
- **Interpretation:**
- Bromine has two naturally occurring isotopes with almost equal abundance, leading to two nearly equal intensity peaks approximately two m/z units apart. The presence of such a pattern is a strong indicator that the compound contains bromine.
Given the pattern observed in the mass spectrum, the compound most likely contains bromine.
**Correct Answer:**
- b) bromine
