My teacher's done some analysis of the pre-release booklet, so I thought I'd share some of the possible questions/topics that any my teacher think could come up.
- PPM -> % conversions
- Knowledge on Ziegler-Natla catalysts (in Storylines p98-100)
- Polymerisation reaction equations
- Intermolecular forces explanation i.e. why does HDPE has a higher boiling point than LDPE (Properties & Structures of LDPE & HDPE)
- There could possibly be a bond enthalpy question on a -O-O- (organic peroxide) e.g. How much energy would be required to break one molecule? Or to work out the frequency needed to break it, vice versa.
- Talking about homolytic fission, maybe an explanation?
- Free-radical initiation of polymerisation with R-O-O-R' molecules
- Propagation & Termination question
- E/Z isomerism question
- There could well be questions on 'gutta-percha' molecules (p105 story), like draw the skeletal formula or draw the full structural formula (from a skeletal formula) and also naming the molecule questions.
- Make sure also you're comfortable with all the homologous series. There could well be a question about the first page about naming functional groups, something basic like that
Hope this was maybe of some help. I'll probably come up with some possible questions on the weekend and post them on here if you'd like
