Out of curiosity, which past paper 2 have people found the hardest and easiest?

Since paper 1 was easy, paper 2 will be harder. After seeing what AQA did to physics students...I won't be surprised if paper 2 is really hard

i found paper 1 so hard - everyone else in my school thought it was great and everyone else it seems - i may be singlehandedly lowering the grade boundaries, need an A and was meant to be my best paper.

I personally thought 2021 was the easiest and 2019 was the hardest based on the marks I achieved on those papers respectively back in the day.

2018 was the worst performed in a typical year - I don’t think it was nearly as hard as 2019, but I can see points where it was easy to drop marks as the marking guidance could be quite harsh.

Another delightful IAL unit 5 synthesis question - June 2020 Q23(b)
See the full paper here: https://pmt.physicsandmathstutor.com/download/Chemistry/A-level/Past-Papers/Edexcel-IAL/2018-spec/Unit-5/QP/October%202020%20(IAL)%20QP.pdf

Solution

can you post some very very difficult calc. questions and nmr and more synthesis, just more hard paper 2 content question from IAL please

I’ll have a look through a few unit 5 papers.

If you spot any questions you are finding problematic, feel free to post them here and I’ll see what I can do about explaining them

Solution

Let’s look at 23(a) from the same paper as it’s a bit of a weird calculation.

Solution

I’m probably being stupid. But why do you need to turn the alcohol to an aldehyde? There are OH’s on both. I understand using CN to add a carbon and then creating an NH2.

I am now going to go through the entirety of Q20 in the January 2021 unit 5.

This one has some rather nasty synthesis questions.

Solutions to (a)(i) and (ii)

Solution to part (b) - VERY MEAN imo

Solution to part (c) - Also rather mean.

You aren’t being stupid - you are learning.

You have to increase the carbon chain length and you are only taught a handful of ways to do it:

-Grignard reactions (required carbonyls)

-Addition polymerisation (requires alkenes)

-Haloalkane + cyanide salt —> nitrile

-Carbonyl + cyanide salt + acid —> cyanohydrin

In that list, there is no method involving just an alcohol. You have to introduce a group that allows a cyanide to be added in. Oxidation to a ketone is the most convenient way as you put the functional group that is required on the right carbon and you can cyanate carbonyls to maintain the hydroxyl group, which remains in the desired product.

I agree with you on 2019 being hard - 2018 seemed like a walk in the park in comparison!

with less then 48 hours to chem paper 2, what would you recommend revising?
I thought paper 1 went well but I havent done any paper 3s and in my paper 2 im scoring close to an A at best, when I need an A
I also learn organic quite late into the year so organic synthesis is a bit of a weakness, apart from that im im weak on just random things in each topic
Would appreciate any responses🙏🙏

Two recommendations:

Try sporcle.com, quizlet or whatever to find quizzes on reagents and conditions for organic reactions.

Attempt some of the past paper questions I’ve been through on this thread and then compare your answers to mine.

Yeah, it was.

How did you find some of the other papers?

Good luck guys, I'm resitting after getting a B last year so hopefully I don't fumble this time

Good luck! Fingers crossed you get an A/A* this time.

From what I heard, last year’s papers were some of the worst on record - achieving a B certainly isn’t fumbling.

yeah but I also made the mistake of not going over the specification so a lot of questions surprised me

I see. The spec is rather crap imo, though.

Hopefully my solutions to some past paper questions above should prove useful for seeing how to approach some unusual question types.

Thank you so much for going through these! For part b, I don't remember ever being taught the products of the iodoform test, is this something separate on the IAL spec, or do we need to know these?

Does anyone know whether we'll be given the Arrhenius equation?
