Chapter 14, Problem 14.16P

Interpretation Introduction

Interpretation:

The cation represented by the given peak has to be found.

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 $\left({\text{M}}^{\text{+}}\right)$, the fragment that results when the molecules lose electrons 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.

Peaks with smaller m/z values, fragment ion peak represent positively charged fragments of the molecular ion.
