Chapter 12, Problem 12.18P

Interpretation Introduction

(a)

Interpretation:

The bond at which fragmentation occurs in the structure of $\text{2, 2, 5, 5-tetramethylhexane}$ is to be stated.

Concept introduction:

Mass spectroscopy is used to calculate mass to charge ratio of ions. Isotopic peak is also known as $\left(\text{M}+1\right)$ peak because it shows one unit mass more than the mass of the molecular ion. This is because the molecule consists of different isotopes of an element.

Interpretation Introduction

(b)

Interpretation:

The mechanism for the fragmentation of the bond between two methylene group is to be stated.

Concept introduction:

Mass spectroscopy is used to calculate mass to charge ratio of ions. Isotopic peak is also known as $\left(\text{M}+1\right)$ peak because it shows one unit mass more than the mass of the molecular ion. This is because the molecule consists of different isotopes of an element.

Interpretation Introduction

(c)

Interpretation:

The structure of the fragment ion of $\text{2, 2, 5, 5-tetramethylhexane}$ at $m/z=71$ is to be stated.
