Question
Chapter 12, Problem 12.27SP
Interpretation Introduction
Interpretation: The compound is to be identified and the fragments corresponding to the numbered peaks are to be stated.
Concept introduction: Mass spectroscopy provides the structural formula in addition to the molecular formula. The bond breaking does not occur randomly, it tends to form the most stable fragments. Fragmentation gives the resonance stabilized cations whenever possible.
To determine: The compound and the fragments corresponding to the numbered peaks.
