    Hi,

    This thread is in advance for people that will be preparing for this exam during the summer holiday to give them a better chance this time next year. Hopefully it will be used up until the exam for revision and help.

    We've done some practicals for reducing ketones to alcohols and the theory behind it, that's it so far

    I haven't done that yet and I don't think it's planned, I know I am making asprin and soap when I get onto the stuff to do with the benzene ring .

    Any chance you can share the theory on this reaction please?

    Sorry I meant the theory behind the practical, we've not gone into the detail yet but all I know is it's nucleophilic addition

    Early bird catches the worm, as they say.

    My college will be starting Unit 4 Kinetics shortly.
    When is everyone getting their textbooks? My college will issue us in Sept.

    Seems like every centre is doing something different, would you like to exchange class notes after the 3 weeks?

    Right, I know it's a bit soon.. But could someone explain how to find the moles in question 1a of the June '12 Unit 4, because it's got me stumped. And it's probably the easiest question ever :P
    Thanks in advance!

    I don't get it aswell, I think there is more to it than normal mole calculations.

    I got as far as:

    1.5+1.2=2.7
    (2.7-2.06)=0.64

    not sure how you work out the moles for each H2 and I2.

    I know that the answer adds upto 0.64 so there is some link.

    It's all so confusing
