    well in the book and mark scheme their first option was HNO2
    oh if the book says then your probably alright, it's just that i a reagent is something you can get out of a bottle kind of thing HNO2 is unstable and must be made insitu, don't worry it's only one mark, how did you find f325?

    trans isomer so trans fats increase the levels of LDLS and HDLS so more cholesterol is transported to arteries and builds up leading to formation of atheroma

    I initially thought there was a mistake on percentage yield as I thought the Mr given for compound e was wrong, talking to a friend after I realised I treated the bond coming out of the paper as an h when it was ch3, meaning the Mr of 160 was correct. I got 61.9 percent or something but I don't think that's right
    i know i did the same i got 61.9 too

    You have been working hard all year...I'm sure you did well
    Thank you too

    it was okay but harder than Jan 2013 for sure, so i am predicting boundaries of 47/47 for an A?


    the structure did you get

    the benzene first then ester and then the methyl stuff

    You're probably right, I'm pretty sure I misunderstood that whole concept!

    The only question which got me tbh, diazonium ion didn't click *_*

    Thanks for explaining

    I think its the way they put N2+ I was so confused but then it clicked :') So it's okay

    Thank god! I put NaBH4 too!

    Otrivine I was so silly on the third one! I put DCPIP instead of 2,4DNP! I was thinking about biology -_-! But I put something about the orange precipitate

    For the second one, I think I got something slightly different but along those lines, can't really remember....

    I found this exam okay! What about you?

    YES that was exactly it. With 2 methyl groups.
    It was definetly harder than January so I think it will be around 47-49 out of 60...but u can never be too sure let's hope for the best
