Which substrates will undergo an E2 reaction to give a (Z) alkene?
What I do know: E2 reactions are concerted and have an anti-coplanar transition state, where the leaving group and the hydrogen being abstracted have a dihedral angle of 180 degrees.
What I don't ...

Why does d/l-2,3-dibromobutane on reaction with NaI/acetone give cis-2-butene?
This is what I have read/know about the dehalogenation of vicinal dihalides by NaI/acetone:
The two halides which are leaving must be on opposite sides (from the mechanism).
In case they are present ...

Elimination mechanism in alkenes
Do E2 elimination reactions occur in alkenes? If not, what mechanism is used?
If they do, are they limited by any stereochemical rules as alkanes do (antiperiplanar)?
My question is pernitent to the ...
