Part II. two unbranched ketone have molecular formulla (C8H100). El-ms showed that
both of them
have a molecular ion peak at m/2 =128. However ketone
(A) has a fragment peak at m/2 = 99 and 72
while ketone (B) snowed a
fragment peak at m/2 = 113 and 58.
9) Propose the most plausible structures for both ketones
b) Explain how you arrived at your conclusion by drawing the
Structures of the distinguishing fragments for each ketone,
including their fragmentation mechanisms.

Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt.
