Answer #1

The compound has peak at 79 and 81 m/z in equal intensity might be due to bromide ion

The compound has base peak at m/z 43 might be due to isopropyl cation

The compound has intense peak at 15 is due methyl cation

Therefore the structure of the compound might be isopropyl bromide

  • The molecular weight of a compound is typically indicated by the heaviest peak on a mass...

    The molecular weight of a compound is typically indicated by the heaviest peak on a mass spectrum, which i presumed to correspond to the molecular ion (M*). For smaller compounds, the heaviest peak tends to also be the most intense peak. The lighter peaks in the spectrum result from fragmentation of the molecule into smaller ions. Since peak intensity correlates to the relative stability of the ions produced, the peaks of the ionized fragments can be more intense than the...
