    Anyone have any tips for revision and for the exam to get the highest marks? I revise and do past papers etc but I'm constantly being caught out by ocr on silly questions and the the lost marks do add up

    I would recommend going through mark schemes and highlighting key terms/phrases and then maybe making some flash cards to revise from. Also try practising 'application questions' from other exam boards as sometimes OCR throw these in to put people out of their comfort zones and test if they actually understand concepts and mechanisms and are not just memorising the text book.

    Good luck!

    Any question which requires more than just rote recall from the specification. Taking F324 June 2015 as an example, questions 2(b), 2(c), 2(d)(i) (second box only), 3(c)(ii) and 4(d) cannot be answered from the specification alone; instead they require application of knowledge learnt on the course.

    Can someone please tell me how to calculate the enthalpy change of combustion and the enthalpy change of formation when given a table? I always get confused from which calculation of enthalpies do I need to take away the sum of products from the sum of the reactants!!!!

    Has anyone tried using questions from other exam boards as revision?
    I spent a little while looking through AQA's syllabus and I noticed that on certain topics the syllabus was practically identical. I read through a pack of AQA's acid/base questions and it seemed really useful, though the questions are of a different style. I wondered whether having a broader perspective of how questions may be asked may be helpful, as it seems that every year people complain that the exam was unusual. Any thoughts appreciated.

    Products minus reactants

    I just quickly draw a Hess' cycle, and remember that formation arrows go up

    I've never really looked at AQA questions but I'm fairly sure some of the tests my sixth form set had AQA questions on them. They didn't seem to different...
    Have you got any access to Hodder questions? They're challenging apparently

    Yeah, that's what I thought when I was looking through. No, I haven't, Ive not heard of those. I have access to the regular past papers and the old syllabus stuff. Our teachers gave us these old syllabus multiple choice papers that were really challenging too.

    Why do alcohols not react with bases but the OH in phenol does?

    I'd recommend sitting down and reading through the book regularly so you can improve your overall understanding of the chemistry

    I believe it's because a lone pair on the oxygen atom is partially delocalised into the phenol delocalised ring, so the oxygen loses some of it's electron density and donates the proton more easily. Something like that.

    Look at the last page to understand, it has little clues when it talks about the FeBr3 halogen carrier. It's open as Br must be on the ends in order to react with benzene correctly, if it was closed and had Br attached (like 1,2-dibromocyclohexane) it would not react.
