that's what I got:smile:what were the states?
That exam was an absolute godsend for me! :biggrin:

I did screw up the 3 marker calculation with the volume of gas equation though. Checked through my paper about 10 times and then only realised at the end, and ran out of time before I could finish it :/ ah well!

the double bond number has to be the lowest, not the methyl groups :redface:

:colonhash: WHY WAS I NOT INFORMED OF THIS EARLIER? :angry:

Aha true, but F335 is so daunting :/

and in terms of types


electrophilic addition

then

elimination?

also... was the half equation
2Cl- --> Cl2 + 2e-


Yup got all of that as well!



Likewise bro. I will dance like a mad man when it's all over! :tongue:

Which one?

2Cl-(aq)->Cl2(g)+e-

And

Na(g)->Na+(g)+e-
For the curly arrow one, I also drew an arrow from the F-H bond to the F, as well as from the C-Cl bond to the Cl and the F to the C. Was this wrong of me? I thought it also produced a positive hydrogen ion which would later go on to react with the hydrogen chloride?
The colour change one confused me...
There was no colour change right... as you can't oxidise a tertiary alcohol? D:

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 :colone:

yay that's what I got :biggrin: it was 2 marks

I think that that's the answer. xD It's what I put.

no your incorrect numbering of methy groups takes priority

Curly arrows from partially negative F to partially positive C then curly arrow from C-Cl bond to partially negative Cl :smile:

Pretty sure you won't get penalised for having the methyl groups with the lower number.

I thought that! I made sure I put the potassium dichromate was orange, to make sure I got at least one mark if I was wrong! I think all you had to do was put "no change as tertiary alcohols do not readily oxidise" for both marks though.
