    When you had to outline the mechanism for the electrophilic addition, they gave us lined space.
    Did you guys still draw the mechanism on top or did you describe it in words?

    i remember getting these for the maths questions on the paper
    KC=10.5 mol^-1dm^3
    enthlapy=-308
    energy of something don't remember what it was as =11760 KJ
    uncertainty as =1.3
    and number of molecules as = 1.01*10^25

    Also for the 6 marker was alcohol due to hydrogen bonding then aldehyde due to dipole dipole and butane due to vdw.I forgot about hydrogen bonding in alcohol so I put aldehyde and alcohol the wrong way round I think I'll lose 2 or 3 marks.
    Other than that I think I may only have lost another two marks in the whole of that paper

    That was the easiest exam I've ever done or seen.

    Do you think they'll accept both distillation and heterogeneous cracking with a zeolite for the seperation of octane and isooctane?
