- Electron subshells
-Atom economy
- Ask us to list principles of green chemistry
- Discuss an instantaneous dipole



Note.... they CAN test us on this.  :knuppel2:

Please elaborate on what points 3 and 4 are. :)

And I seriously doubt they would put on sub-shell configurations.

Well if they put anything to do with subshells, I'm definitely getting them wrong.

Even if they did give us something on those I'm sure it'd only be one measly MC question anyway ):

considering sub shells is not even highlighted in the study design and its highly basic and dosnt involve the type of chemical understanding the examiners are looking for... id give you money if they put it on

I'd say at the most there would be a multiple choice on subshells.

Can, but highly highly unlikely. Unit 1/2 stuff IS assumed knowledge i.e. sub-shells and instantaneous dipoles, but I really don't think VCAA is that cruel to pull out something that is purely unit 1/2. Atom economy is easily testable. The principles of green chem are more likely to be applied than listed; I don't think VCAA wants you remembering a list of 12 things. The principles are pretty logical anyway.

Atom economy is following the formula which most of the state has forgotten, it would be cruel (then again it is VCAA that we are talking about) to test that out and I believe it is the most likely of the option that they would put onto the exam.

Is atom economy:

number of atoms in desired product / number of atoms in reactants   OR...

molar mass of desired product / molar mass of reactants   ?
