    Is it in the spec though?

    I put Platinum at room temperature :/ The past papers I've been doing were always on off about nickel when I put it down
    I put both (pt one in brackets)

    The colour change one confused me...
    There was no colour change right... as you can't oxidise a tertiary alcohol? D:
    fml messed up on that one I wrote orange to green - I thought it was aldehyde they were talking about in that part of the question :mad:

    I remember my teacher telling us it, you would have to check as I dont have the spec handy

    what was the hydrogen question? because I remember writing H2 gas + platinum catalyst at RTP :confused:
    You can use those reagents and conditions as well

    no, I didn't include the HCl part, it was just my logic as I went through inner turmoil with 5 minutes left deciding whether or not to add another arrow!
    Aha, so long as you got in the end

    This was my biggest guess at an answer

    I wrote..

    2O2- + 4H+ + 4e- --> 4OH-

    is this right? I am 99% sure it's not haha

    the frequency one was 3 s.f.

    I could swear I checked hmmmmm
    ahh yes, i think you may be right

    For the propan-1-ol and propene, did you says the propene=ID ID and propan-1-ol=hydrogen bonding?

    If you go to chemical ideas pg 277 all the questions have the X-ene bit with X as the lowest number (either equal to or lower than the numbers of the methyl groups)

    Yes propene ID-ID, propan-1-ol hydrogen bonding therefore stronger and more energy needed to break and I did a little diagram :P

    If someone can help me out we can make an unoffical markscheme!

    Alkene
    ether

    electrophilic addition
    anhydrous sodium sulphate
    distilation
    Nickel catalyst, 150 degrees and 6atm/ Platinum catalyst at room temp + pressure
    tertiary alcohol- 3 carbons
    No colour change as tertiary alcohols can't get oxidised.
    C10H16
    H2O
    Isomer drawing
    Didn't get naming the compund right, some methyl octane business...

    LDPE property: High tensile strength (I put good electrical insulator )
    CFC- chlorofluorocarbon

    The 2O2- cancels out, so you're left with water reacting with the H+ ions to give you 4OH-

    for the property of the electrical wire, i put it was water resistant.

    Would that get the mark?

    780000000 was an answer to something and the diagram for N2O

    I don't know I hope it is!

    I think water resistant gets the mark

    I put water proof because it said ALLOW in a previous mark scheme, so hopefully
