Title: VCAA sample Exam
Post by: Dark Horse on May 16, 2009, 08:09:47 am

Hi, I was wondering if someone could put up the answers to the VCAA sample exam, because I have not been able to find them

Thanks :)

hmmm...i've been hearing that the 08 sample exam is pointless since it was waay easier than the 'real deal'.

It's still good practice.

Q4 a) on the '08 Unit 3 sample exam. The hydroxyl one was obvious but is the double bond a functional group as such? That's what the CEA answers say but I just always didn't see the double bond as a functional group so just checking.

Also, when writing equations for organic pathways do you use the molecular formula or the semistructural formula? And do you show states (I was told always show states but even CEA doesn't show them)

Also, when writing the strucutre of compounds, do you show lone pairs where they affect the shape?

Also, when writing the -OH substitution of a chloroalkane to form an alkanol, then do you use OH- as the reactant or NaOH/KOH?

I remember that question, it is very ambiguous.

When writing equations for organic pathways, it's better to use semistructural formula. Always show states, but don't automatically assume (aq).

As for structure of compound, you don't have to show lone pairs, but if you want to there's no punishments.

OH- is the reactant for that substitution. Having NaOH as opposed to H2O will just mean the reaction is more readily to occur.
