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. The table below includes data from the two sites: http://dailymed.nlm.nih.gov/dailymed/druginfo.cfm?id=7130 http://wiki.medpedia.com/Clinical: Neutrospec_(Technetium_(99m Tc)_fanolesomab). a. b. C. Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away).
