Ketones are useful starting compounds in organic synthesis.
This question is about butanone.
The mass spectrum of butanone has significant peaks at m/ z = 43 and at *m/ z *= 57.
i) Give the structures of the species responsible for these two peaks.
(2 marks)
ii) Give the structure of one other species that you would expect to produce a peak at a different m/ z value in the mass spectrum of butanone.
