I have now completed the revision guides for the new syllabus for OCR Chemistry A.
Find them at the top of the page https://chemrevise.org/ocr-revision-guides/
The old syllabus guides are at the bottom of the same page.
I’m sure there will be some typo’s to be corrected and things to be improved over time!

Hi,
For the new Chemistry A level (AS) specification, do we need to know about formation of Esters?
I know it was in the old specification, but I can’t seem to find it in the new spec.
Has OCR taken it out?
Thank you
Sama
From my memory, this is a change on the new spec
literally made an account just to comment, your notes are insane, god bless you, thank you so much for taking the time to help me pass my A level, hope you get everything you want
