Advanced notice paper F332 OCR SALTERS B

Yes, but I got taught that two lone pairs = bent, 1 lone pair = pyramidal, no lone pairs = tetrahedral... I know that's for 4 areas of electron density, and ozone is triatomic like you say, so surely it wouldn't be bent- it'd be something different that applies to 3 areas of electron density.

I see what you mean. What do you think it should be?

I'd say it's bent purely because in the advanced notice it says it has a similar shape to a molecule of water so I'm assuming that it's somehow because of the double bond between 2 of the Os... that's as far as I've got though

We were given some exam style questions on the advance notice:

and here are the answers
Hope this helps anyone

We haven't gone through the pre-release yet... we haven't even finished polymer revolution. Does anyone else have difficulty completing a WHOLE past paper due to the fact they haven't had the chance to study the pre-release for that specific paper. It's really putting me off revising

thanks, you just made my revision much easier!

Same here! i feel so lost and i also don't think my chemistry teacher will go through advance notice either

I uploaded that, it's homework for easter so I should have the answers by Friday, I will upload the answers ASAP after I get them

SAME! We have finished all of our lessons completely but our teachers have failed to even mention reflux and have not gone through the pre-relesae! Whaaa!?

If anyone would like to explain to me about what refulx is and where we use, that would be really helpful ??

YUPPP same here! i dont even know how my teacher expects good grades tbh

if you've got a cgp chemistry book read that because it really explains it well. but anyway, it is heating volatile reactants in a vertical pear shaped flask with a condenser so they do not escape. it is also a very slow process. anti bumping granules are in there to let the mixture boil smoothly and prevent shaking.

Also no refux for me. What is it about Chemistry teachers that decide to leave gaps in our knowledge when sending us into our exam?

We've missed out quite a bit too, thank goodness for 'Niel's notes'

Neil's notes?

Hey Thank you so much for uploading them; they're super helpful! Could you maybe upload them sorta soonish please?? (and sorry if I'm just being thick and not seeing them if you have already :P)

Notes that a member of staff at my college made, covers everything with diagrams etc

the files are too big to upload though
