    Attachment 223164I got 2ethyl6methylhept-2-ene too
    At your 1 and 2 carbons you should have gone up the ethyl bit instead, which gives you a chain of 8 carbons. But hopefully it'll get a mark because it is KIND OF right.

    I believe if you draw out 2,6- dimethyloct-5-ene it's exactly the same- are there any specific naming rules for this, or are they both allowed? How many marks was it, in case they aren't
    the double bond number has to be the lowest, not the methyl groups

    Some questions;

    1. Was the alcohol tertiary?

    Yes

    2. Will 0.78 x10^9 be ok...

    I'm not too sure. If you give it in standard form, I think you have to write it in the proper format of the number being less than 10 and above 1

    3. For the curly arrows... what did you have to do?
    I drew an arrow from the lone pair of F to the C
    then 4 arrows from the covalent bonds to the Chlorine atoms...

    I think you would only need one arrow from the bond to the chlorine atom, but I'm sure they won't mind that!

    I got tertiary
    It should be cos thats the same as 780,000,000
    I did the same for the first arrow but then I drew only one arrow from one covelant bond to the chlorine :/
    I did what you did one arrow from the f to the c then one arrow from the c to the cl

    The number of the double bond has to be the lowest starting point, so if you were taking the double bond as 3 and not 5 (which is the rules) then the methyls were on 3 and 7.

    At least F332 is the big chunk

    any thoughts on the grade boundaries guys?I hope theyre low but judging by how everyone found it i'm guessing probably 75-80 for an A

    Was the "Hydrogen" thing...
    150C nickel catalyst.. for the conversion one...

    and the equilibrium;

    decrease for higher temp
    increase for higher pressure?

    Quite a few people have been tripped up on the naming one last part Q1, the NaCl one and the bromine one at the start from what I have seen.

    Maybe 76 or something

    Yah! But I still don't get how F335 has the lower weighting than F332. Salters is messed up
