    I'm so stressed about the organic toolkit.

    Seriously. I can barely remember it, at all. I could probably scrape through if asked about synthesis of halogenoalkanes/primary alcohols/secondary/tertiary, aldehydes, ketones, and -COOH and esters.

    Amides/amines AND all the benzene reaction conditions can go suck a ****.

    What are the things that people are finding hardest to revise for? I'm struggling with being able to bash out azo dye synthesis :/

    So who has memorised all of the organic toolkit? Also, how did you do it?!
    I copied out the reactions from the revision guide. and split them into batches of four.
    From friday, I did 8 everyday, spending an hour each day on the organic reactions... now I can recite them like a poem . So you could possible cram all of it by wednesday. but I would focus on the arene ones and esters

    Well you're a better person than I am!

    I've been focusing so fricking hard on biology, I haven't paid nearly enough attention here. Turns out I could have revised biology by watching countryfile, but that's another matter...

    I'm going to just keep repeated all the reactions and conditions, and ram the arenes into my brain tomorrow.

    I#m just so worried about this.

    for the person that wanted all the answers to module tests and stuff :
    http://benjamin-mills.com/chemistry/sac/
    its for 2nd edition but most of the questions are the same.

    Storylines URGH!

    also for why are things coloured, I always put this and it seems to get all the marks when my teacher gives me papers back.

    When light passes through a solution/substance, a photon of light may be absorbed. This photon of light carries the energy required to promote an electron from a lower to a higher energy level. This /\E (i dont know how to put those triangle things on the computer) has a corresponding frequency (as in the equation /\E = hv). if this frequency is in the visible region then the substance will appear coloured (the complementary to that which is absorbed). Different dyes can be differernt colours as modifier groups and changes in delocalistion can affect the /\E and therefore affects the colour.

    Then adapt that to what the question is. ALso references to orbitals can be con (as im told) so dont put that in unless asked.

    Im so screwed for wednesday.

    wrote each reaction on a separate piece of card. and selected 8 to memorise. did 4 in the morning, 4 in the afternoon.
    the did all 8 together in the evening and I still remember them

    Just random groups? I guess you split the aliphatic ones into two, and the aromatic ones into two?

    Im sooo scared, this paper is so synoptic KMT !

    I just hope that question about why is a compound coloured comes up lol

    Is there any chance someone could put these practice papers up? I'm pretty sure i haven't done them all.
    Thanks in advance.
    I don't think i have a hardest topic but i have drawbacks in all of them :/

    A little question for you bright tsr'ers
    How would you properly define a conjugate base pair? Could you give me a little detail about them please, I seem to have a very small, confusing set of notes on them :/

    guys could u just clear this up plz... what are the conditions u take into account when calculating pH of a weak acid and a buffer? also is the value of KA = to the value of hydrogen ions??

    I don't think you need to really take any conditions into account. You only really need to with strong monoprotic acids, as you have to assume that all the H+ ions 'react'.

    You need to assume that everything dissociates/reacts with everything else. ie, [HA] -> [H+] + [A-], and that there's nout left over.

    IS THIS RIGHT OR AM I STUPID? I'm just trying to remain calm.
