azo dyes???

on the physics & maths tutor amines practice questions i keep seeing questions about azo dyes and diazonium ions - i have no idea what these are and have def not been taught it so im guessing theyre just old spec questions but could someone confirm for me that theyre not on the a level ocr a spec please! :smile:
If they're not on the spec then obviously you don't need to know about them.

They aren’t on the spec for OCR A. Afaik only OCR B actually still covers them, so you don’t have to worry about them.

Edit: the chances are that the diazonium questions that you have seen are just old spec questions or ones taken from OCR B.
