can answer simple learning outcomes you say very smart alr haha
if can do h3 pharm then maybe
-
Can anyone post the ans to P3 if they have it?? thanks :)

last question haha why is the condition for chlorine to react with phenol Cl2 in Ccl4 and not Cl2(aq) for question 5? Saw afew on reddit saying Chlorine in CCl4

Haha james do you think cl2aq should be accepted?

Hi, if for question 2a, my colours are stated wrongly (it was correct at first but i went to cancel it.......) but i included all the explanations like oxidising strength equations and e cell values, how many marks will be deducted? :(

Isnt cl2 aq the answer???? Just like br2 aq? -

I'm not sure either but my school(JJC) taught us Cl2(aq) also allows trisub for phenol, not sure whether if it's accepted tho

1st one brown solution, second one reddish brown, 3rd one brown? -

The colours were a key criteria of the question, so i would think they allocate one mark each for each colour.

3rd one contains aqueous iodine, so should be pale yellow, though brown might be possible

I think our school teaches us aqueous bromine as reddish brown, and aqueous iodine as brown.... so all the reactions and calculations only worth 1 mark?????? -

1). non-polar solvents
2). liquid
It should be half half for colours vs explanation
-
Lol the qn didn't specify mono or tri-substituted phenol so both should be accepted la haha they won't be so stingy with the marks
the second and third one how to displace. Both halogens are less reactive than the halide what. so colour remains unchanged for the last two.

But then the 3rd reaction is aqueous iodine, shouldnt it also be brown like the 1st reaction? Omg then our school teaches us wrong stuff... -

Time to look at economics!

You also taking h2 econs? -

though like this year econs i think must study the learning outcomes properly one by one

Lol you prediciting which topic for essay? I doing globalisation,macro problems and market failure -

i think essay better to do demand supply, market failure and one macro-you are safer that way-because its easier to hit the mark on micro

Demand and supply is the worst qn to ever do... even our teacher warn us to skip it. Very risky and easy to go completely out of point -

If they throw you the markets and it is a straightforward question, it is worth a read. Foreign policy is harder to justify and evaluate compared to micro concepts. Who knows if your examiner isnt a staunch anti-trade guy?
In any case, the key to scoring for econs is always to provide balanced arguments. Once youve hit there, it is a likely L2 and then a little bit extra will push you to L3.

Yup true, i think it is just that our school teachers do not want us to take the risk. anyway all the best for math paper 2, honestly speaking i hope that it is not too easy, so that the bell curve will not be too high...
