    True that, I totally forgot about PVC etc I think i'll get 1 mark for that bit
    To be honest, you may get the mark for purify, it just depends upon how pedantic they will be in the paper on marking.

    I put flame retardants for the other use of CFCs is that right? and what does CFC actually stand for?
    (Original post by super121)
    Chlorofluorocarbon
    Oh snap, apparently CFCs did use to be used as flame retardants. The MS should acknowledge this

    hahahaha, damn that would of been a good way of remembering it. Nice I put chlorofluorocarbons, thought it was a hard paper though. Hopefully 75/80 for an A
    I'm hoping for maybe 70-72 for an A

    Yeah I didn't think it was too easy or too hard, it was standard I'd say

    Did anyone get 1,1,5- trimethyl hept-4-ene for the name of the molecule by any chance. It seems right to me when i work it out, but everyone seems to be writing other things...
    It is in fact 3,7-dimethyloct-3-ene.

    Its this because the double bond must be on the smallest numbered carbon possible (In this case number 3 carbon) and then take the longest chain (8 carbons = octene) and then put the other groups in which is 2 methyl groups left on the 3rd and 7th carbon.

    And there we have it.

    Yeah but it said intermolecular bonds which means between molecules, I was thinking that at first but pretty sure that's what intermolecular means.

    I can confirm that the shape of Nitrous oxide (N2O) was linear.
    I have no idea why I didn't put linear, I got the dot and cross right as far as I know but then my mind just went off it
    Do you think I'll still get some marks for saying electrons repel, as far apart as possible, etc.

    What did people get for the overall equation when you add the two equations together? They even managed to make that hard when it should be one of the easiest things! grr

    No, it was tertiary because the OH was bonded to a carbon that was bonded to 3 other carbons

    I thought it went well but afterwards I knew for sure I got two questions wrong ! (Luckily they were only 1 mark questions)
    But still ! Who knew a one marker question could stomp you in an exam for ages
    The rest went well though ... *Breathe*

    Hope it went well for everyone
