    I put diol instead of triol! Haha, I'm sure you haven't done as bad as you think though, just keep positive and TRY to enjoy your summer.

    Probably 47 for an A, 43 for a B 39 for a C.
    Haha thanks! Hopefully I will have got a B. Think F325 went a bit better so hopefully I will still have an A overall. Oh well... knew I'd screw up Chemistry anyway. I still have 2 exams left

    I think reduction or nucleophilic addition becasue your adding the Hydride nucleophile?

    How did u explain the trans fats in CHD question?
    Presence of a double bond means restricted rotation around the double bond as both carbons are attached to two different groups as a result, the isomer which is currently in its cis form could change to trans. The trans form means that the molecule packs more easily and becomes a solid more readily as a result an atheromtous plaque builds up in the coronary arteries leading to heart disease....

    The percentage question I got 63.2 I got the Mr of the compund G which was 174

    and then did the moles divided by the moles
    I got 63.2 aswell and yes it was, but the correct structure is only usually 3 marks the rest of the marks would be from working out

    not sure but the book put the phenylamine reacting with HNO2 and HCL?

    it was alright and you
    yeah that is right for the equation, but the reagents technically should be NaNO2 and HCl as HNO2 is made in situ

    NaNO2 + HCl ----> NaCl + HNO2

    the HNO2 and HCL and Phenylamine all react, but you can't add HNO2 you have to make it in situ,

    yes and splitting patterns and analysed the carbon nmr, I didn't actually say heptet I multiplet for that one but did name others , both are accepted on previous m.s though

    read the book, they put the benzene what ever reacting with the HNO2+HCL
