    Unit 6 is on Friday. I'm more nervous about that :/ I mean, writing that 10 mark answer needs a lot of thinking and stuff
    And I do hope for the second question, they don't introduce some new mathematical concept.
    oh good luck with that. hopefully they wont dont really understand what ur talking about tho i still havent taken A2 yet

    I wrote add potassium IV dichromate and it would change from orange to green :P
    PCl5 is the correct test,A tertiary alchohol doesn't react with potassium dichromate and H2SO4.You can't use that test.The question was about confirming OH group.Carboxylic acid also has OH group but it doesn't react with potassium dichromate and change color from orange to green.

    Really? Thought that was for the presence of alcohols since the reaction is
    For example
    C3H7OH + PCl5 ---- C3H7Cl + POCl3 + HCL

    That IS strange though,I haven't that happen before in any school. Atleast you aren't taking other subjects at the moment I assume.

    Neither does mine,It's not compulsory or anything but you CAN do it.Although no one I know has DONE both AS and A2 at once,They've given some AS Papers in A2(Either due to bad grade or because they didn't give them in AS)

    Your realization was correct.Physics is basically like a leech that sucks the life out of you,You can't handle that with a lot on your plate already.
