Could anyone link me to where I can find all the legacy/old past papers? I've seen the ones on the OCR website but they're in the form of a zip file and it's all mixed up with other irrelevant files...


I use: http://pastpapers.org/chemistry-a2-papers and http://www.sci2.co.uk/chemistry.html
Some of the files don't work, not sure why but most of them should be there. Hope this helps!

Here:
Questions:

* Describe TLC and GC in terms of what the stationary and mobile phase is and how the components are separated.

* State the use of GC-MS in analysis in forensics, environmental analysis, airport security and space probes.

* Explain how GC-MS can be used to identify a compound.
Are you meant to put brackets around polymers like Terylene when showing a specific number of repeat units (i.e. not n)? :s-smilie:
If it asks you to draw a repeat unit i don't think you have too. brackets are just used round one identical unit to the rest should you ask i don't know to circle the repeat unit. im not sure though

Oh okay thanks, I have an inconsistent mark scheme from my college which is making it difficult to know which is right! :rolleyes:
