    Would be alright to put cracking instead of thermal cracking as the name of the process of breaking down long chains into small chains? It becer said what type of cracking like in jan just **** is the process called
    A good point. You might well get away with 'cracking' here - it depends on the feedback from the papers.

    For the question about why Hydrogen bonds would not form, would it be okay to say as the molecule contains no Nitrogen, Oxygen or Flourine atoms, and Hydrogen bonds only form between Hydrogen atoms and Nitrogen, Oxygen or Flourine. Everyone seems to have wrote something about electronegativity
    I doubt it. I think electronegativity difference is the only thing that will score here.

    My chemistry teacher looked at the paper and he said it would be what I said, he could easily be getting confused though I hope I get credit for it!

    I hope so, but in my experience with this specification it seems unlikely.

    Yeah, AQA can be horrible when it comes to mark schemes

    for the question which asked us to predict the bond angle, will I still get the mark for stating 109 degrees?
    Yes....I put 109.5 degrees....but i have seen a few mark schemes which would accept something between 108-109.5.
    But I think they will definately accept your answer....so don't worry....you can't do anything about it now anyway.

    really ? i drew 2-methlyprop-1-ene
    Yes so did I...I just hope it could be that as well, cos I messed up the above ques and said that it was but-2-ene and lost marks for that also

    This isn't a functional group isomer of the alkene in the question because it contains the same functional group. Cyclobutane or methylcyclopropane are the only things that will score here.

    I didnt round my answer to 85.6 for the realtive atomic mass question, i out 85.57, will i still the marks ?
    and also, for the cyclobutan, did u have to say "CHCH....." or did u have to draw the molceule ?

    I dont think that one will be posted online now because many schools use hat paper for mocks. You could probably find the question paper if you look hard but it's going to be almost impossible to find the mark scheme.
