hey there, off topic but i see your doin mpharm, what did you put as your insurance
im having a hard time choosing, deadline is thursday

yup, mines a 2nd resit lol, went down on my first resit. good luck.

How do you guys think Chains and Rings went?

thought foundation was ok, got the crystalised water thing wrong though, i said it was bonded but it wasnt.... do you include the water in the mass? also was the negative ion so4 (2-) trying to work out roughly how much i need in my other modules now!

It was pretty damn easy, I thought. They were basically taken from previous papers by the look of it.

Should be an easy A. How about you?

was a lovely paper. anyone do HFHF aswell? thought that was a bit harder

Chains and Rings guys,what did you for the last question on the paper, reagents, conditions and draw the product I drew Propan-1-ol and propan-2-ol.

Thanks for that, for the long written answer I wrote all about Fractional Distillation, then Cracking, reforming and Isomerisation, then ethanol can be regrown by plants and combustion equation, I needed extra paper to complete this answer, even though I am a grade E student in chemistry. What did you right about the oxidising agent, the fuctional group and what happens in the reaction?

I wrote alcohol - functional group
acidified Dichromate
Orange to green

I know my fuctional group is wrong, others in my college wrote carboxylic acid, so your answer probably is right. I completely messed up the structures on this question, didn't have a clue, what did you write for the number of isomers and why alkenes have cis and trans?
