I wish.. I swear I read on another thread that you took biology a year early?? You're clearly the genius here :smile:

Cambridge are idiots!

Yeah I did. anddddddd got 99% overall :cool:

(it was pure fluke though)..Unfortunately, I'm not as good in chem :frown:

Yeah. I.hate.cambridge. :mad:

:O It's not normal to get 99% overall in a year!! It's weird I used to be miles better at chemistry (98% last year) but now I'm way better at biology.. strange.. It's physics that'll kill me though!!

Also, has anyone got any C-13 NMR questions - I can't find any on the old papers :confused:

Yeah, it seems like they never test on that.

On question 1 b ii, is it just me or is there a mistake on the mark scheme? Because that equation does not look balanced to me.

Nope, don't think so.

Does anybody have the June 2005 paper, with the actual spectroscopy graphs? They have been removed due to copyright restrictions in the paper I've got :frown:

I have learnt that mechanism, with cyanide addition, just in case. But yeah, all we need to know that it's useful in organic synthesis at it extends the length of the carbon chain.
