Yes, sleepy head, rise and shine with Chemistry
Yeah... we can call it anything. But Electron donating and Electron withdrawing is better. ur rightI think it'd be better if we call the Ring Activating group ' Electron donating group' and the Ring Deactivating one ' Electron Withdrawing group'.
Thanks for the points.

Yeah, but what would your observations be? Why not use aqBromine? What does the marking scheme say?http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s09_qp_4.pdf

Yeah, that's an alternative answer..but it doesnt say reject aq Bromine now does it?
The marking scheme never said anything abt aq bromine. that means its ok. the iodoform test is an alternative.
Oh come on. check again. The first phrase for 6(b) is Aqueous Bromine.
ian not saying that br2 is wrong what iam asking is that is diazotizationn coupling correct or not?
