Chapter 9, Problem 17PP

Interpretation Introduction

Interpretation:

The given mass spectra figures are to be matched with the given compounds.

Concept introduction:

Cleavage of a single bond produces a cation and a radical. The cation can be detected using positive ion mass spectrometry and since the radical is not charged, it will be undetected.

Chain branching or cleavage of a single bond at branch points will occur such that the carbocation formed is more stable.

Carbon-carbon bonds adjacent to atoms with unshared electron pair break readily to form carbocations that are stabilized due to resonance.
