Yes I know. This thread is nothing to do with the Olympiad, they're not going to ask for this - but I've had experience with plenty of undergraduates and even postgraduates and to me this doesn't seem like many first or second years chemistry students would know it.
Originally when I mentioned it you said the Olympiad exams looked similar to your first-year stuff which seemed more reasonable, since what they ask from us is mainly to learn from first-year textbooks in preparation.
Can I see some of your first-year exams then? Essentially I'm just looking for hard and clever problems, if the theory is first-year uni stuff I'm happy to give it a shot.
I understand it may seem pretentious of me to label my posts "Undergraduate" but I can't think of any other way to avoid responses containing info I already know. The issue is that if I label some of these posts as "Sixth Form" I will get responses that are designed for AS-level board exams and that is a level well below the Olympiad problems. I can tell this most acutely because - I do both!
This is what I'm looking for. I don't mind if they make approximations; when I said "exact" all I meant was "not VSEPR guesses". If it's quantum mechanics there's going to be some approximation anyway I'm guessing.
Where can I find out about the maths involved?
Edit: And don't deny it - you're not taught the quantum mechanics of bond angles in the average first year course!
