Chapter Overview
Chapter 17, 'Qualitative Analysis (Mass Spectrometry)', introduces key analytical techniques used to identify molecular structures and determine atomic weights. It covers isotope analysis, measuring relative abundances of isotopes, and calculating relative atomic masses.
The chapter focuses on molecular mass determination by identifying the molecular ion peak and interpreting molecular structures through fragmentation patterns.
Finally, students will learn to deduce the number of carbon atoms in a molecule and identify the presence of chlorine and bromine using specific M+2 and M+4 peak height ratios.
