=Dehalogenation of vicinal dibromides= Can anyone explain a bit of the reaction mechanism here? From a student's perspective, a few lines about the reaction mechanism makes a process like this far easier to remember. If I can find a good source, I'll do it myself sometime soon. Also, does this only work with bromides? We're calling it dehalogenation, but if it only works with vicinal dibromides, it'd probably be more clear to call it debromination, as many others do.

=Cahn-Ingold-Prelog naming of isomers=

Uh, E is same side and Z is opposite.


 * Uh, no: E is short for 'entgegen' which any German will tell you means 'opposite' and 'Zusamen' means 'together'. See E-Z_notation


 * Thanks for taking an interest. Glad it's educational! Ewen (talk) 22:37, 17 March 2008 (UTC)

=Stuff Removed= I've removed the following reactions: Corey-House reaction (this is used in the synthesis of Alkanes, not Alkenes. Catalytic Dehydrogenation to produce Alkenes (this is an industrial procedure and not used in labs). -- Pete 15:31, 25 November 2006 (UTC)


 * Hi Pete


 * (you're up early today!)


 * I think the more important industrial reactions should have a place in the book. Certainly courses such as A-level and the IB include some industrial syntheses as well as lab preparations.


 * I'm one for lumping everything in once place, as you've probably noticed. I've moved the EZ notes from Chirality and left only a brief mention there. Anything extra to the EZ notes you put under alkenes I've tried to merge there. Is that OK? Ewen 16:03, 25 November 2006 (UTC)


 * Yeah, that's all fine. Oh, I just looked at it closer. I didn't realize what Corey-House was. That's just coupling of a Gilman reagent with an alkyl halide, right? I've never heard it called that. That belongs in haloalkanes anyway since it goes with the Gilman reagent synthesis. As for catalytic dehydrogenation, I'll add it back. You're right, it should be there. -- Pete 02:57, 27 November 2006 (UTC)

Anti markonikov rule,why the HCl & HI are not follow the rule ?
