OCR F324 (Chains, rings and spectroscopy) 28/06/10

C; just on the boundary , you?

If you oxidise an alkene apparently you get two different aldehydes 9I don't remember ever being taught that, nor is it even mentioned in the book.) I believe the June 09 paper (q7) has a question on it.

Can someone help me out please? i have no idea what the integration trace on nmr means...it's supposed to show the proportions of protons but i have no idea how it does...can someone please explain it? and please quote me when replying

Ah damn, the exams way too soon!!
I haven't even done enough meaningful preparation!
Anyone got any tips as to what I should prioritise- Rote learning or past papers??

just go thru the spec. theres one hundred pages in the txtbook for this paper. you could probs get thru it all in one day. ive only started revision today. just about finished module 1. make sure u know both mechanisms for this part.

Yeah I agree; just go through the specification finding out exactly what we need to know; I revised Module 1 in the May half term, so all I have to do is the short section on Module 2 and then the Analysis section which I hate!

Apart from going through the spec, I just do the lastest past papers and F324 from Jan 2010 again;

take a look in the link posted in the post before yours, if your struggling with nmr spec. i posted the link last week, and since discovering this teachers videos on nmr, i havent messed up on an nmr question since. theres more detail than required for our spec, but it'll certainly help with your understanding.

my chem teacher has been **** and lazy for the last 2 years, so ive basically had the job of teaching myself. and my best resource has been youtube. another channel to take a look at is by a youtuber called: khanacademy. his vids helped a lot with biology, mind i havent checked his vids for chem, but if his bio vids are anything to go by, i'd recommend him.

Thanks for your consideration ; I have looked at this video before and found it quite helpful as well; but it is not so much NMR that I hate about the analysis section it is more about the stuff about chromatography and spec points (a) through (h) under chromatography.

Can anyone help?
What's the difference between an amide link such as in polyamides and peptide links in condensation polymerisation of amino acids?
They're both c-o-n-h ...

theres no difference, just a diff name

So do you reckon they can be used interchangeabley without losing any marks?
