    why is there three separate marks for each paper? where did you get this from?
    It says above ''Grade boundaries 2009-2011 (A/B/C) - that's why there's three marks for each. I got the grade thresholds from the ocr mark schemes, they're usually on the first page of google if you search for them by year. The averages I just worked out, and the boundaries for this year I've predicted.

    You know for the last question I put the line above the solid would I still get marks for labelling the arrows even though the line was in the wrong place (it ses it warms the solution not the surroundings so I thought it was endothermic looooooooool)

    Yes, you do get marks for the two arrows.
    One is enthalpy change of hydration and one is enthalpy change of solution.

    Yes, I do.
    The hydrogens are in 3:1 ratio.

    Nice drawing by the way.

    Yes, but the other way around, was it okay if the single Hydrogen was on the end of the side with 2 Brs?

    Ha, I didn't.
    And yeah, that's what I got. Though I wrote it out instead of drawing it.

    I also wrote GLC for the one your talking about

    i guessed that!
    but i dont understand the spectrum
    the ppms dont even indicate a H near a Br?
    Im really confused?

    That was hard. I put that because the S(total) of the reaction is very high it would need a lot of energy to kick start the reaction. And the fuse would provide a high enough enery/temperature. And then I waffled a bit.

    That's wrong but oh well.
    I thought the paper was hard. For that question I wrote the same as you but completely made it up. Hope it gets us some marks.The long answer questions were ok though.
    What did people write about the polar bonding question? was 5 marks

    Same thing since single bonds can rotate, so yep

    You're right, the chemical shifts didn't match up with the regular values, but I'm sure it was okay because the question did not ask for any information about chemical shifts in your answer..

    Carbon is delta positive. Halogen is delta negative. Halogen is bigger so it attracts electrons more strongly.

    I can't remember what else I put. What was the whole question?

    Yeah got exactly that But the chemical shifts didnt match the ones on the data sheet. Then again it didnt tell us to mention any chemical shifts. Just the splitting pattern and hydrogen environments etc.
