What will be the alkene product of this elimination reaction?

I think it should be a bromo-alkene

Which bromine and hydrogen will be removed first?

In my opinion the right one


Stability maybe
Actually I don't remember the reason but afaik Br in the middle will stabilize the compound

I think it should be an alkene with a double bond between the middle carbon atoms and with one bromine atom at the terminal carbon

Oh yes ... You maybe correct I didn't consider rearrangement ... But which would be more stable ? The compound I told or the compound you told?

Is it alkyne formation reaction.


Alc. KOH is not a strong enough base to further react with alkene. The above product would have been the answer if NaNH2 was used in place of alc. KOH.
