Question
Chapter 12.15C, Problem 12.11P
Interpretation Introduction
Interpretation: The peaks at
Concept introduction: Mass spectroscopy provides a reliable molecular weight for an unknown compound and also gives us the information about the molecular formula as well.
Fragmentation gives the resonance stabilized cations whenever possible. Loss of a small molecule is usually indicated by a fragment peak having an even mass number corresponding to loss of an even mass number.
To determine: The peaks at
