happy to help. Ngl, it's kind of the same approach with a mixture of memory and process of elimination. The main difference with organic analysis is the problem solving and puzzle aspect of the questions, this involves FAR more practice using past papers etc., making sure to use the AQA insert for IR spectra, NMR spectra info etc. so that you're familiar with it once you get to the actual exam. Best of luck! lmk if you have any questions
video for you on a 6 mark organic analysis question :) I go into a lot of detail throughout, so feel free to skip through to parts you find helpful! ruclips.net/video/K9-YDFfn5Mw/видео.html
Sorry I'm not him but do write everything in pen. The pencil will disappear when scanned by the examiners. You can use pencil on graphs tho when working something out but pen on everything else! Don't want you to lose marks that way:)
For aqa guys you need to show the delta position and negative in the mechanisms, otherwise you will lose a mark , most of the mark schemes in aqa require it ! And a common misconception is that you do not need to show it 😢
Please let me know an example question that this is the case and I'll check out the mark scheme, I've seen it say many times 'ignore partial charges unless incorrect'

@@easymodeexams33 there’s also a few other that have required partial charges because I kept not drawing them out and I found in my topic tests my teacher kept saying I’d loose m1 for missing them
And here’s the examiners report for the questions , this is what they had to say Q4. The nucleophilic addition-elimination mechanism in part (a)(i) presented a real challenge to many students, who were confused by the cyclic nature of the product, failed to identify the correct nucleophile and suggested either separate nucleophiles such as H2O, CH3OH and OH- or alternatively loss of the proton from the OH group before nucleophilic attack. Most students gave the correct M3 structure however students failed to show partial charges on M2 and ignored them loosing that mark even though correct structure was shown or had suggested C+ instead of delta partial charges.

Wow I’ve been searching the difference between benzene and phenyl for months and you’re the only one who properly explained it i understand it now!
Haha awesome!
watching this 2 hours before the exam...
Same, A* incoming
This is amazing, glad I found this a month before my a level exam lmao, thank u
haha no worries! You've got this, just keep practicing and learning from your mistakes! :)
More like a day
How did it go

Hi could you do a vid explaining naming priorities?
Omg yes 😭😭😭
Thank you, this was really helpful. Do you have any advice when it comes to answering analysis questions?

Can you please make a video on nomenclature?
Can we draw mechanisms and displayed formulas with pencil in the exam or does it have to be with a pen?
Sorry I'm not him but do write everything in pen. The pencil will disappear when scanned by the examiners. You can use pencil on graphs tho when working something out but pen on everything else! Don't want you to lose marks that way:)
Do with pencil first, when you're sure of your final answer then rewrite with pen.
If u make mistake, it would be messy to correct with pen
thank you!!!
No worries 😄
If I write the brackets and n, do I lose the mark?? Even though I got the unit correct?? Wth?!?

• M2 not allowed independent of M1, but allow M1 for correct attack on C+

thanks for taking the time to find this Zara, I'll look into this properly and leave a comment with any corrections/details for others to see.
