hah lol unlucky
as i said above i thought it was okay, though the question about berylium and barium chlorides completely threw me, apparently BeCl2 is covalent and BaCl2 is completely ionic, which is not what i thought :s

wasnt the berylium question about the charge density? and the forces of attraction between the cation and anion??:s-smilie:
yea i put 1-hydroxy 2 amino propanoic acid so thts down the drain, also the becl2 is covalant as it has a small highly charged cation and it polarises the cl- anion completly , Ba the radius is too large for a strong force of attraction to occur, not the actual answer just an overview

thats what i thought, which lead me to conclude the exact opposite of what my teacher said was the answer :s
That paper raped me and my friends!

It was the hardest paper (along with Jan 2004) ever.

The polyamide and polyester question which were each 2 marks, I did not do.

The first organic question was extremely sneaky, 9 MARKS?!?!??!?!

But the thing that struck me most was not the content of the paper, it was actually that it went on and on and on and on.

I found time became a very large issue for me, with an additional 10 mins I would have put a couple of more marks in the bag.

Really gutted with this paper. I did not do too badly though, its just that I was aiming for an A.
