Chapter 16, Problem 16.77P

Interpretation Introduction

Interpretation:

The formula of a compound that can give rise to the given mass spectrum is to be determined.

Concept introduction:

The mass spectrum of a compound is often represented as a bar graph with m/z on the x axis (where m is in atomic mass units, u) and the relative abundance of ions at each m/z on the y axis. The mass of each ion is just the mass of the atoms that make it up. The ${\text{M}}^{\text{+}}$ peak of a mass spectrum is taken to be the compound’s molecular mass. The presence of bromine, chlorine, or sulfur can be identified by the relative intensity of $\text{M + 2}$ peak.
