QUESTION:

How could their mass spectra be used to distinguish between the following compounds?

ANSWER:

Solution 16P

We can distinguish the given carbonyl compounds based on their fragmentations and the relative intensities of their peaks in the Mass-spectrum.

(a)

The compound is as follows:

The compound on bombardment with forms a molecular ion that undergoes fragmentation and forms fragment ions that are detected by the instrument, exclusively positively charged species.

The compound shows a fragment peak at and a base peak at .
