Interpretation Introduction

(a)

Interpretation:

The structure of the fragment in the EI mass spectrum of 3-amino-3-methylhexane at m/z=72 is to be drawn and a mechanism of its formation is to be stated.

Concept introduction:

In mass spectroscopy, compounds are identified on the basis of mass of compound. When the compound breaks into fragments then they can be distinguished from the other compounds. This technique is also used to differentiate the isotopes of compounds. This technique does not involve electromagnetic radiations. Two peaks are used to identify the compound, the molecular ion which is the mass of the compound and base peak is the peak of most abundant element.

Interpretation Introduction

(b)

Interpretation:

The structure of the fragment in the EI mass spectrum of 3-methyl-3-hexanol at m/z=73 is to be drawn and a mechanism of its formation is to be stated.
