OCR AS - Chemistry Unit F322 - Chains, energy and resource - REVISION!

GOOOD LUCKKK EVERYONEE SITTIN THIS EXAM oh god unit 2 is so much better then unit 1

Yeah exactly the mistake I made, thus I am retaking this unit again!
Just make sure your organic chemistry is good and your sorted. I have done A2 so this should be alot easier I am hoping

How do you mean? Meaning.. are the old spec papers not good to do? Because, for F324, i got high A's in every old paper and got a 'D' in the real one im retaking that alongside this.. and what you said about the old past papers is probably true now! So how do we prepare????

Okay so alot of people have asked me this, and this is my $0.02.
Forget the old spec, its good for practise but there is no way in hell that the exam is going to be as easy as it was in the old papers... so bare that in mind. If you get 100% in the old spec does not mean you will be getting that in the new one.

All I can say to you is UNDERSTAND it, for example why is a nucleophile a nucelophile, or why how do you get 1,2di-bromomethane from a reaction mechanism involving radicals.
Dont just remeberize the content, you will get a C max. Also the OCR book is good to get you about a C/D grade- this is what my teacher said. DO ALL the papers from 2009-2011 (new spec). Understand the MS, and then I think this is a golden tip- I used it for my A2 unit 1 paper (which has alot of organic chem) is to just randomly draw isomers of molocues, both skeletal and displayed. Do random reactions and see if you can find a pattern.

I really wish someone had told me this before january so i didn't get excited when getting A's in old past papers. Terrible shock in the exam

Yep thanks. So recent papers is the key.. got it. Do the old ones but just for practice, dont get too happy about it 'cos it betrays you in the end

No problem I would also reccomend the tutorials on youtube- absolutley immense for module 2 AS and module 4 A2!

Don't worry, I made the exact same mistake you did last June... But I learnt and there's no way in hell I am letting that happen again!

One more tip guys... IF YOU CANT do a question, just leave it. Don't piss your time up as 1hour 45 mins is really tight in the exam.

It really isnt

would you recommend the book the OP featured over the textbook?

Carboxylic Acid + Alcahol (Acid Catalyst)

You guys above really don't understand how the game works...

What is the bond angle in an alkene? and shape?

Around the C=C atoms, it's trigonal planar, 120.

What happens to the rate of a reaction if you decrease the temperature? Why?

Define Stereoisomer

molecules with the same molecular and structural formulae but have a different arrangement of the atoms in space

define first ionisation energy

haha, here we go third time lucky



I believe the answer is 'a molecule with the same number of atoms but a different arrangement of atoms in space'

But it depends on whether or not its structural or stereo isomerism

ok next question

what are primary, secondary and tertiary alcohols oxidised to? (state reactants and conditions)

actually the answer is a molecule with the same chemical formula but a different structural formula, a steroisomer is the same structural formula but a different arrangement of atoms in space
