Chapter 9, Problem 6Q

Interpretation Introduction

Interpretation:

The given statements about mass spectrometry that are trueare to be determined.

Concept introduction:

Mass spectrometry is the detection of ions on the basis of weight and charge and their abundancy after the formation of ions.

Mass spectroscopy is a graph with mass ($m/z$) of ions on $x-\text{axis}$, where m is the mass of the ion and z is the charge of the ion, and their abundancy on $y-\text{axis}$.

Molecular ions formed by EI mass spectrometry are high energy species. Fragmentation of the molecular ion means that a complex molecule is broken into smaller molecules and these fragments can undergo breaking and so on.

The ($m/z$) with the highest relative abundance is called the base peak.
