    Did anyone do the OCR chains energy and resources re-sit today? (Year 13)
    If so how did you find it?
    Yes and it was amazing

    Can someone please clarify this because I've seen it different on 2 different markschemes
    Is it that benzene cannot induce a dipole in Br2 but phenol can or induces a dipole less than phenol in Br 2 - confused which is correct
    Also would it be correct to say pi-electrons or pi-bonds when describing the bonding in benzene?

    probably that benzene can induce a dipole less than phenol but not strong enough to polarise br2.

    You can say either I think, for the newer papers it says benzene polarises bromine less and then it has Allow benzene cannot polarise bromine/cannot induce a dipole. I just did a 2010 paper again and it didn't have polarises bromine less on the ms but I assume that was because it's old?
    I think you can say pi-electrons or pi-bonds it doesn't matter either

    Hey does anyone know if we can access the specimen papers for other years? I ran out of F324 papers and just found a specimen paper but there's only one on the website. Idk if they produce them every year or just when the spec changed in 2010? Thanks

    please help with question 6c
    It would be G and F alternating but with H's in between them since G and F are Di carboxylic acids so they can't bond to each other only to H? So GHFHGHFHGHFH. What paper is that question from?

    Hi guys, would much appreciate the 'markscheme definitions', for:

    addition polymerisation
    condensation polymerisation

    I know what they are as a concept, just not sure what marking points are looked for.

    Yeah that's correct. Would like to know the paper also

    Condensation polymer:
    Monomers join to form polymer AND produce small molecule/H2O

    Addition polymer definition isn't on spec but it should be:
    Unsaturated (C=C) monomer is saturated (-C-C-)

    Hi,

    I think the one on the website is the only one.
    Just do the legacy papers on pastpaper.org?

    Hi, I will be taking OCR chemistry a level next year and was wondering what your opinions are of it. Is it hard? and do you recommend any revision books that I could get in advance.
    Thanks

    At first it all looks ridiculously hard but, as with anything, once you get to the end of the course you realise how straightforward a lot of it is.

    The hard part is teaching yourself to learn in a way you really understand something rather than trying to memorise answers. If you don't understand it you'll get ****ed in the exams.

    As for learning material, the specification has changed so it will be different to what we've just done.

    Its a new spec for you as the previous year was the last. Make sure to get textbooks reccomended for YOUR new spec (2016/2017 onwards)
