We will look at some of the major peaks in the mass spectrum of butane.

The molecular ion has an m/z ratio of 58.

It produces a peak here.

If a carbon–carbon bond breaks here what peaks will form as a result?

The CH 3 CH 2 CH 2 + ion has an m/z ratio of 43. It produces a peak here.

The CH 3 + ion has an m/z ratio of 15. It produces a peak here.

If a carbon–carbon bond breaks here what peaks will form as a result?

The CH 3 CH 2 + ion has an m/z ratio of 29. It produces a peak here.

This is a simplified mass spectrum of butane. Further fragmentation is possible.
