Chapter 10.4, Problem 8P

Interpretation Introduction

Interpretation:

Primary alkyl halide has to be identified from the given mass spectra.

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 in mass spectroscopy is used to explain the number of carbon atoms present in a molecule depending on the abundance of ${\text{(M+1)}}^{\text{+}·}$ peak.

The ${\text{(M+2)}}^{\text{+}·}$ peak: It denotes the peak that arises next to molecular ion peak in the mass spectrum with respect to the presence of major isotopes in the molecule especially it is used to find the presence of chlorine and bromine since they has two isotopes.
