Chapter 15, Problem 50PP

(a)

Interpretation Introduction

Interpretation: The signals in the mass spectrum for the given compound $\text{2-bromopentane}$ should be explained under given conditions.

Concept Introduction:

Mass spectroscopy: It is a form of spectroscopic technique which is used for the elucidation of the molecular formula and molecular weight of the compound, depending upon the mass of the molecule.

Molecular formula: It represents the types of atoms with their total number present in a given molecule.

Molecular ion peak ${\text{(M)}}^{\text{+}•}$: It is defined as the heaviest peak in the IR spectrum of the molecule which represents the largest molecular ion in the given molecule with greater m/z value.

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

The ${\text{(M+1)}}^{\text{+}•}$ peak: It denotes the peak that arises next to molecular ion peak in the mass spectrum. The peak arises due to the presence of the isotope of carbon $\left({}^{\text{13}}\text{C}\right).$
