Transcribed Image Text:**Mass Spectrometry Patterns and Isotopic Abundances: Identifying Bromine**
In mass spectrometry, there are patterns in the molecular ion region due to isotopic abundances.
**Task:** Identify the pattern that would correspond to a molecule containing one bromine.
**Graph Details:**
The image contains five mass spectrometry patterns labeled I, II, III, IV, and V. Each pattern depicts peaks at mass/charge (m/z) ratios labeled as M, M+2, and M+4.
- **Pattern I:** Peaks are at M and M+2 with the same intensity; no significant peak at M+4.
- **Pattern II:** Prominent peak at M; smaller peaks at M+2 and M+4.
- **Pattern III:** Peaks at M, M+2 are of similar intensity; smaller peak at M+4.
- **Pattern IV:** Prominent peak at M; moderate peak at M+2; smaller peak at M+4.
- **Pattern V:** Peaks at M and M+2, with M being more prominent than M+2; smaller peak at M+4.
**Options:**
A) I
B) II
C) III
D) IV
E) V
**Note:** Identify which of these patterns corresponds to a molecule containing one bromine, considering bromine's characteristic isotopic pattern (approximately equal intensity for M and M+2 due to the presence of isotopes Br-79 and Br-81).
Expert Solution
