Chapter 10.5, Problem 10P

Interpretation Introduction

Interpretation:

The molecular formula that exactly matches given mass value has to be identified.

Concept introduction:

Interpreting a mass spectrum:

1. 1. The each m/z values is the m/z value of one the fragments to the nearest whole number.
2. 2. The peak with the highest m/z value in the molecular ions (M⁺), the fragment that results when the molecules lose an electron as result of being bombarding by the electron beam.
3. 3. The m/z value of the molecular ion gives the molecular mass of the compound.
4. 4. Peaks with smaller m/z values, fragment ion peak represent positively charged fragments of the molecular ion.
