    C1 might be harder this year..

    The grade boundaries are trending to increase.

    6 marks:
    Polymers? Limestone?
    Could you explain the conditions needed for polymerisation? I think they are a catalyst and high temperature, but I may be getting confused with cracking?
    Thanks

    Don't worry, they're in C2.
    Does anyone have any hard questions they've come across before, I want to practice some or similar ones so I know if I can do hard ones I can do the easy ones.
    Let's hope it's not like B1 :s

    Do you reckon it will be like that disastrous biology paper? I'm getting so scared

    I wish they make the chemistry paper hard. 😄

    I have a feeling that it will be hard and focus on Limestone and Polymerisation.As they are experimenting the new syllabus on us!
    I also predict that there will be a question about underage smoking and mice being high. <----- these are only predictions so don't just focus on them :P

    do I detect a dig at the biology paper there? 😂

    Someone please tell me about polymerisation and limestone? I've revised everything but I'm a bit weak on those topics and I can't find a lot.

    I thought you had to know them briefly.

    Thermosetting polymers have cross links thus a higher boiling point.

    Thermosoftening polymers have weak inter molecular forces thus weak forces of attraction.
