Edexcel A-Level Chem Paper 3 General + Practical Principles in Chemistry [Exam Chat]

topic 15 and 18 are two main ones that will most likely come up.

See the post immediately above

what is even likely to come up on transition metals? havent seen very many questions on them

do you just recommend looking at the methods for all of them?

I'm so fed up of this honestly

ikr i cant wait to be done with these stupid ******* exams

I think stuff about ligand reactions and catalysis.

fr this has to be the most vile exam. ALL of chem AND ALL of practicals... 2 and a half hours... and its an application paper... after a week with 3 exams in 3 days

it would have been good if this paper was a bit earlier in the exam series rather than being the last paper.

nahhhhhhh
you on crack bro
imagine having to do this paper without having already revised beforehand everything for the other two papers
that would be ******* impossible

i meant after paper 1 and 2 but before the other papers. if that makes sense.

I’m guessing a long mark synthesis question will come up as it didn’t come up in paper 2. Also another long mark NMR question where you probably have to work out the structure of the molecule using proton and carbon spectra data. Maybe some Zwitterion questions as well. Then the rest of the paper will be a bunch of absolutely disgusting practicals and a hideous titration calculation worth 5 marks. That’s my prediction. Then the following weeks after the paper my prediction will be that I will be physically crying every night and considering whether or not to withdraw my UCAS application because of how badly the exam went and I don’t want the extra pressure on results day when I inevitably fail and have to face the rejection email from my uni, then I will probably start applying for resists next year. Anyone else have any predictions?

well, I just hope the synthesis question involves grignard reagents as that would be more doable and it would be good if the nmr questions aren't worth more than 5 or 6 marks.

i still dont understand grignard reagents...can someone explain

Halogenoalkane dissolved in dry ether and reacted with Magnesium to form R-Mg-X [GRIGNARDS].
When Grignards is reacted with Methanal it forms a primary alcohol
When Grignards is reacted with any other aldehyde it forms a secondary alcohol
When Grignards is reacted with Ketones it forms a tertiary alcohol
When Grignards is reacted with CO2 it forms a carboxylic acid
