I have updated the notes on the mass spectrometer to match the recent supplementary information added to the AQA website and the specimen questions.
The revision guides for the new Edexcel syllabus are now complete and can be found here https://chemrevise.org/3-edexcel-revision-guides/
The old syllabus guides are still there on the same page
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!
I have created a few new chapters for the e-textbook on the year 12 organic chemistry content. Remember the e-text book is not tied to any one syllabus and has more detail than the revision guides. They all contain relevant questions (some of which are more demanding or more open ended than a usual A-level paper).
If you are just starting your A-levels in September 2015 you will be doing new brand new syllabi. I have started the process of updating the revision guides to reflect the changes to the structure and content of the courses. The new AQA guides are now largely complete and I have posted them here. (There are two guides that are not quite complete but these will appear in the next couple of weeks.) They exist on the same page as the old syllabus guides which are still valid for present yr13 students.
The new OCR and EDEXCEL guides are not yet complete but I hope to be posting them before the end of the September. The old guides are still 95% useful for the new courses in the meantime.
I have made a few more chapters for the e-text book.
2.12 Electronic Structure This covers quite a lot of background information beyond most A-level syllabi
2.13 Ionisation Energies This chapter has a couple of pages of questions on ionisation energies at the back
3.11 Introduction to Enthalpy Change This chapter goes into some detail about enthalpy changes for background reading
3.12 Hess’s Law This chapter has 3 pages of questions at the end
3.14 Bond Enthalpies This chapter has 2 pages of questions at the end
There are not currently answers to the questions
