E2 Mechanism Help
« on: December 22, 2013, 02:37:29 PM »
Hello

I was wondering if anyone can give me some guidance as I am completely stuck

                                                                                                                   Br
Question states: Treatment of 3-Bromohexane which I know to be (CH3CH2CH2CHCH2CH3) with potassium tert-butoxide (K+(Ch3)3(CO-) give 4 isomeric Alkanes (all with formula of C6H12)

What is the mechanism and draw the alkanes?

Now I am pretty sure that the Mechanism is E2?
I am semi-sure that there would be 2 stereoisomers and 2 Structural Isomers (from my knowledge) but I can't draw them? I am having massive difficulty. Addition and substitiution I can do well but elimination is driving me insane.. Any help or guidance?

What does the word elimination mean?
And do you not mean alkenes?

I meant what is the definition of elimination as opposed to addition, for example?
What is addition?
Try searching the fora for an answer to your question, it is a relatively common question.
