Chapter 2, Problem 100PS

(a)

Interpretation Introduction

Interpretation: For the mass spectrum of $B{r}_2$, the molecular species give peaks at $\text{m/Z}$ ratios of 158, 160, and 162 are needed to be determined.

Concept introduction:

Mass spectroscopy: It is a form of spectroscopic technique which is used for the elucidation of the molecules, depending upon the mass of the molecule.

Parent ion peak: It is defined as the prominent peak in the mass spectrum of the molecule which represents the not fragmented molecular ion in the given molecule with greater m/z value.

Base peak: It is the tallest peak in the spectrum.

$B{r}_2$ ionize to form positive ions, $B{r}_2{}^{+}andB{r}^{+}$.

Elements present in $B{r}_2$ are ${}^{79}Brand{}^{81}Br$.

Interpretation Introduction

Interpretation:

For the mass spectrum of $B{r}_2$, the relative intensities of the peaks has to be explained.
