OK, here's the deal,
I need to come up with a GCSE level chemistry question to stump my teacher, and frankly I have no idea what to put.
help required!

Ask him: when you mix benzoquinone with an equal portion of to 4-nitro-2-hydroxy-aniline in ethanol with 2 equivalents of acetic anhydride (anhydrous) in ethanol and stir for 2 hours at room temperature - what do you get?
ans: 1,2,4-Trichloro-7-nitro-3H-
phenoxazin-3-one

Take a simple question and use very vague wording (kind of like what you'd find in your average exam). State no assumptions and don't give any extra information. Then, you can always say teach got the answer wrong because you REALLY meant such-&-such when you asked the question.

"Why don't electrons fall into the nucleus?" is a good one, and will sort out good teachers from bad ones.
