### Analyzing Mass Spectrometry Data For the following mass spectra, determine: (a) The presence or absence of Cl and Br (b) The molecular weight of the molecule (c) If it is consistent with an odd number or zero/even number of N atoms (d) Parent Peak (e) Base Peak #### Explanation of the Mass Spectrum Graph The graph presents a mass spectrum with varying intensity peaks on the vertical axis (not labeled) and m/z (mass-to-charge ratio) on the horizontal axis, ranging from 0 to 100+. Key peaks are labeled as follows: - **18, 19, 27, 31**: These lower m/z values often represent fragments. - **39, 41, 43**: Mid-range fragments indicating larger molecular structures. - **59, 65, 69, 77, 84**: Higher m/z values indicating significant fragments or possibly characteristic ion peaks. - **101**: Circled on the graph, potentially indicating a significant peak such as the molecular ion peak or base peak. Additional notes on the graph indicate neither Cl nor Br is present. Use this graph to determine the molecular formula, weight, and significant isotopic patterns. Consider the absence of peaks indicative of chlorine or bromine, likely ruling out their presence in the analyzed molecule.

Transcribed Image Text:### Analyzing Mass Spectrometry Data
For the following mass spectra, determine:
(a) The presence or absence of Cl and Br
(b) The molecular weight of the molecule
(c) If it is consistent with an odd number or zero/even number of N atoms
(d) Parent Peak
(e) Base Peak
#### Explanation of the Mass Spectrum Graph
The graph presents a mass spectrum with varying intensity peaks on the vertical axis (not labeled) and m/z (mass-to-charge ratio) on the horizontal axis, ranging from 0 to 100+.
Key peaks are labeled as follows:
- **18, 19, 27, 31**: These lower m/z values often represent fragments.
- **39, 41, 43**: Mid-range fragments indicating larger molecular structures.
- **59, 65, 69, 77, 84**: Higher m/z values indicating significant fragments or possibly characteristic ion peaks.
- **101**: Circled on the graph, potentially indicating a significant peak such as the molecular ion peak or base peak.
Additional notes on the graph indicate neither Cl nor Br is present.
Use this graph to determine the molecular formula, weight, and significant isotopic patterns. Consider the absence of peaks indicative of chlorine or bromine, likely ruling out their presence in the analyzed molecule.
