**OFFICIAL THREAD** OCR A AS Chemistry F322 2nd JUNE 2015

Obviously OCR

is the first one ethanol? i don't know what it means by the solvents

chemistry solvent question.docxanyone know how to do this?

What is this from?

Did the new specification not start 2009? I don't think that is in the course anymore.

There is likely a reason why however if you're worried, just remember that one is a substitution and the other is an elimination. The outcome just depends on what the solvent is.

What is this from?

W - water
X - ethanol
??

Thats right but how do you work that out??

idk, i do 2 papers everyday and feel alright but tbh i havent revised that much...

I don't feel prepared either
But don't worry! As long as you stick with past papers and know the content you should be alright. How many past papers how you got left?

i just done them all today, my plan is to do all the past paper, Sun and Mon to memorise stuffs and Tuesday morning to do last year paper again to prepare
This plan worked for Unit 1

That's good . I might redo the june 14 again, it was quite a tough one

ikr, right in the first question when they ask for polymerisation of cyclopropene

True, i still don't know how the reaction of bromine with cyclopropane gave 1,3-dibromopropane, do know that?

Sorry, how can the single bond be broken? I thought alkanes don't go under addition reactions?
