II.8 Report on Radicals
(Value 1 quiz grade due Tuesday November 22)
Write a 7 page report that:
1) Explains what a free radical and charged radicals are and how
they differ from an
ion such as an anion. Mention which is more stable, i.e. which has a
longer
lifetime in general.
2) Explains the following statement "Chain transfer refers to
transfer of a "chain reaction" i.e. the free radical, not the polymer chain."
Give an example of a
reaction that
does not involve a polymer chain but which has "chain (reaction) transfer".
3) Expains the role of free radicals in biology and how
vitamin C can act as a free radical scavanger in the human body. (Linus
Pauling's role in this topic should
be noted.)
You should mention your opinion of the effectiveness of vitamin C at preventing
cancer and colds.
4) Outline Lenz's section from chapter 11 on chain
transfer in polymerization reactions, CT to monomer, solvent, polymer, initiator
etc.
