    That's fine it would be alright for any suitable reagent
    Br2 would just show a clearer colour change and is normally used in experiments so it would probably be more common for people to put that
    for what?

    We didn't do any mechanisms therefore I think the following will come up:
    -Mechanism(s) of any reactions
    -Ozone depletion
    -Group 2 and trends
    -Analytical techniques e.g. MS, IR...

    Any others?
    Collision theory?
    Identification of ions?

    -Types of bonding e.g London forces
    -History of the periodic table
    -Catalysts
    -Polymers
    ALSO:
    -Boltzmann Distributions
    -Energy Profile Diagrams
    -Alcohol Reactions (only came up in MCQ)
    -Possibly esterification

    You seem to have this under control. What textbook/ revision guide/ material did you use?
    Didn't really prepare specifically for this exam i.e. cram the night before but I learnt the content with the school textbook we were given which was the Oxford one
    It goes into more detail than needed but it helps with understanding

    What do you use?

    There were plenty of tests for ions questions that came up today though...

    Do you reckon we will get directly tested on HSW stuff they have on the spec like that triad stuff from GCSE?

    Well this looks like a lot of work

    2 marks worth wasn't it? One MCQ and another 1 marker?

    Yes so there is not much more they can ask about except test for NH4+

    We don't do esterification at AS.

    Any others?
    Electronegativity (posssibly Pauling values, van Der Waals, permanent dipoles)
    Practical questions - maybe titrations, standard solutions, organic synthesis as in separating and purifying products
    Hess' Law?
    Rate of reaction
    BOLTZMANN is very likely imo
    Bonding (giant covalent, simple molecular etc)
    Properties of alcohols and alkanes


    Basically the stuff that hasn't come up but it's still a good idea to go other the stuff that we've already revised and have a look at the specification.

    Well defo be tested on the practicals weve done. Thats certain. Theyll be putting HSW into those.
    And I used CGP. Big mistake. They drift over everything trying to simplify it.

    If you mean the last last question, you had to substitute hydroxyls in the place of halogens through nucleophilic substitution, you can't just add oxygens


    I think (read: hope) two marks
    ... Well there goes my grade. Gosh, I really hope they don't have a high grade boundary.

    I used 100 as they mixed the two solutions together
    But the other one was in excess..

    I swear Hess law came up today? The combustion one.

    They still have a right to test 'unfamiliar scenarios' to stretch and challenge so although it's not directly on the spec they can still give you enough info about it and ask you a question or something on it

    It's unlikely though but it was a GCSE topic I think for most exam boards

    was the shift position in the le chet. question to the right? and in the second (Kc) part, to the left?

    It might come up again as in the more complicated/unfamiliar onesName:  Screenshot_2016-05-27-12-07-27-1.png

    I've got the CGP guide but didn't use it much through-out the year as I felt it over simplified everything, especially some of the IR diagrams they have

    I guess it does cover key points though

    I also used the spec through-out the year as well which is quite useful
