    any idea of grade boundaries? the last exam you only needed 70% raw marks to get 80% ums, so I'm hoping its the same this year, but a teacher told me that they have high grade boundaries for this exam because they don't know how well people will do in the coursework, and then they lower the grade boundaries for the final exam if to compensate...what do you think?

    did anyone else write addition and condensation for the cross linking crap??? what a laod of bull that question paper made me want to pick it up and slit my wrists with it.
    Yes

    Noooooo! Leave slitting wrists for the results day (hopefully NOT though! :p: )

    Your teacher is wrong, they will make the grade boundaries of this exam depending on how people do in it, not on the coursework lol

    I cant remember that well, but i think put Br- as the reducing agent? Or did i put O3? Well what ever i put it took me 5 minutes to come to an answer
    I put Br- hope its right/

    Pretty sure it's Br-. LOL

    How about the question ... er something about how different enantiomers react differently in the body (2 marks)

    A reducing agent is oxidised, the Br- lost electrons to the oxygen.

    I put that the different enantiomers are different shapes so interact with the active sites in proteins differently.

    Same, and that optical isomers behave differently in the presence of other chiral centres e.g. in nose (?)

    It was awful. The bloody question about nappies?? What was that?! Hoping for low grade boundaries. Its so annoying, in both my mocks i got a substantial A, but this was awful! RETAKE!

    I didn't write down any examples I really can't see where the 2 marks would come from in my answer

    They're definitely going to raise the grade boundaries for this one. It was pretty easy.

    different shapes so different enzyme catalysed reactions

    There were bits about both. You had to draw an E/Z isomer, but there were two questions about optical isomers and enzymes.

    It was, yer. They still have different shapes though

    I'm pretty sure it was talking about enantiomers....
