Chapter 21, Problem 21.67SP

Interpretation Introduction

Interpretation: The structure of an unknown compound, its consistency with the observed absorption and fragmentation that account for the prominent ion at $m/z$ $69$ and smaller peak at $m/z$ $99$ is to be stated.

Concept introduction: A method by which structure of compound is determined by the interaction between matter and electromagnetic radiation is called spectroscopy. A spectroscopic technique in which infrared radiation is used for structural study is called IR spectroscopy.

To determine: The structure of an unknown compound, its consistency with the observed absorption and fragmentation that account for the prominent ion at $m/z$ $69$ and smaller peak at $m/z$ $99$.
