(a)
Interpretation:
The structure of the ion at
Concept Introduction:
Mass spectrometry is an analytical tool that determines the mass to charge ratio of molecular ion. When solid, liquid, and gaseous substances are bombarded with high energy electrons, they ionize and meanwhile fragmented. The detector detects the charge to mass ratio of the ion and produces spectrum according to their abundance.
Nominal mass is the mass of molecular ion of most abundant isotope, where mass defect is not considered.
(b)
Interpretation:
Reason for intense peaks at
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The reason behind the one clean peak in chromatogram has to be explained.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
Atoms that are labeled with deuterium has to be determined.
Concept Introduction:
Refer to part (a).
(e)
