The new study design, now that midyears have gone the way of the purple spaghetti monster!
Ethene is no longer an option as a selected industrial chemical for detailed study in Unit 4. Presumably not enough schools were doing it.
Personally I was hoping to see some of the Unit 4 Outcome 1 stuff introduced in Unit 3. It'll be interesting to see the sample exam they put out, for the kinds of questions and how they amalgamate the two units.
Units 1 & 2 are more or less the same, from first glance.

And this is in the wrong board.

wow, that's interesting... sucks to all the '13 grads who have no practice exams! :D

moved to the right board now.
Also there's a summary of changes in this document here (click the chemistry link): http://www.vcaa.vic.edu.au/Documents/bulletin/2012/2012julsup.pdf

They can do all of the practice exams dating back to 2000, just excluding the odd question :P And they don't have to sort through Unit 3 and 4 exams pre 2007 like we did! It's more the 2.5 hour exam covering an entire year of material which will screw them over.
-
Are we seriously that screwed? In terms of content, do you think we're better off with some of the topics gone, or doesn't it make much of a difference? Will it be harder?
-
You aren't really screwed, you'll just have to make sure to constantly revise and do practice questions from Unit 3 throughout the year.
-
Interesting, from what I can see, they don't have to specifically learn the instrumentation/function of chromatography/spectroscopy, just how to analyse readouts from them
-
principles and applications of chromatographic/spectroscopic techniques (excluding features of instrumentation
and operation)
The bit in parentheses is interesting, that certainly wasn't part of the current course. Maybe they feel it would be too much to remember for the 10 odd chromatographic/spectroscopic prcoesses on top of all the other Unit 3 and 4 stuff? Personally I found it to be really interesting, especially with NMR, IR and Mass-spec.
There's nothing in the new study design about fractional distillation either, something that was fairly involved in this year's Unit 3 exam. Also it specifies now the 'production of biochemical fuels' rather than just 'biochemical fuels' so maybe students will have to learn about actual production processes? Similarly to sulfuric acid?
-
They'll be fine exams of first year of every study design are always easy. In the end they are all in this together so they will all still be ranked accordingly. GOOD LUCK YEAR 12s OF 2013!!

Hahaha, tell that to the people who did Psych last year :P

15 marks alzheimers i heard? haha they covered it in like a lecture slide at my school, everyone was so mad

Not always the case. Look at the A+ cut off for the 2006 Biology mid-year examination (54/75). That exam was definitely as tough as nails.
-
Doesn't look like there's any major changes from when i did it, not that there needs to be for a year 12 level, chemistry isn't moving at the rate of say bio.
This one stuck out to me:
• comparison of energy sources: types, uses and sustainability of sources including brown coal, natural gas, nuclear fission and biochemical fuels
VS
• comparison of the renewability of energy sources including coal, petroleum, natural gas, nuclear fuels and biochemical fuels
It seems like they're focusing less on use (eg. ethanol is for cars) and some of the chemistry behind it and more on the sustainability.
Changing world but i think it was better as it was.
-
There wasn't really much about the chemistry of it though, unfortunately - I don't think it's ever come up in a Unit 4 exam. All we learnt in class was the energy transformation and combustion equations. Stuff about synthesis was done in Unit 3. I think they've just made the wording more concise.
-
Do we have to get back to pre 2000 exams or older? Or those with Unit 3 and 4 exams(or recent ones) should be fine?
-
Doing the same exams that we did (2008-2012) should be enough. There's more than enough there anyway. Prolly do about 10-20 Unit 3 exams and 10-20 Unit 4 exams, depending on how much time you have.

Hey charmanderp,
I am not sure what things I should leave out from learning these holidays? ( I am doing the first few chapters) What do they mean by we don't have to specifically learn the instrumentation...etc.???? Should I just do the whole chromatography chapter(for example) anyway?
Yours Sincerely,
PoiBoy
-
I think he means that we do not need to know the mechanisms of each instrumental technique. The description given in the textbook is a simplification; the actual procedure is much more complicated in real life. I think you only really need to know how to interpret graphs and spectra, but not sure since I haven't read the study design in enough detail.
-
So I could just skip the bits in the textbook that talks about the instruments itself (like the parts of a mass spectrometer or how it works etc?)
-
You could, but you'd be wise to learn them. The more you know...

Not a particular priority though.

Just read in the study design: "addition reactions of alkenes (addition of hydrogen halides and water limited to symmetrical alkenes"
Ive read nothing of the sort in my textbook; the fact that addition reactions involving water only occur for a symmetrical alkene

same here! :) just realised we didnt have to learn asymmetrical alkene (maybe cauz i didnt read the SD properly) . But i learnt it for u3 , so...?

so if it pops up on the exam, youre all good lol. But it says limited to symmetrical alkenes so if something does come up on the exam, i will find those who wrote it. Even still, i read that alkenes react with steam to form alkanes (with phosphoric acid catalyst at 300 deg)????
Unless steam is classified as water

Dw too much about it. The chemistry is pretty much the same except that with non symmetrical alkenes there its more than one product if you add say hcl
