Thank you so much for all the videos you post!! Honestly, you're saving my A-Levels!! You explain topics in such a simple way, and manage to condense nearly all the information into a short video. Thank you again!!
Thank you, I love you. Such a good pace of teaching. My lecturer wen through it too quickly for me to fully absorb this info. You are a god of a man, thank you.
These videos are great for my revision. Could you possibly make a few videos on past papers and how to tackle difficult question (applying knowledge) especially unified concepts paper. Please
hi sir I did my paper 2 ocr a today but im so worried as I drew all my structures in pencil will they still be picked up and will I still get the marks ?
im a bit confused on how you got the splitting for the last 3 environments, because environment 3, i thought it would be a triplet as its attached to environment 4 and has 2 protons so using n+1, it would be a triplet. and as for the multiplet, i thought it would be a triplet too like for environment 5???
Jazz Tan each H is done separately, if more than one H is in the same environment then the peak gets bigger. So, each of H3 is adjacent to one H4, so is split once into a doublet. There are 2 H3s though (each next to an H4) so the relative integral is 2. Each H4 is adjacent to an H3 and an H5, so is split twice, but the splits aren't equal because the Hs aren't equivalent. This makes a multiplet at a level difficulty. H5 is split by 2 equivalent H4s, making a triplet.
Will these videos be enough to get a good grade - like is it covered in enough detail? I've not started chem yet so I'm unsure whether it's good enough

You are a saviour

Thank u, great for a revision break!
Are these videos for the chemistry A level OCR course A or course B

ohh right i see! so you get multiplets if one proton is attached to carbons that are in different hydrogen environments
Truly
Your my maths teacher

Yea these are great. Obviously do past papers but these do cover the content pretty well
fml if only you or someone could do the samething with biology snab new spec
