Predict all alkenes that would be formed by the dehydrohalogenation of the following halides with sodium ethoxide in ethanol and identify the major alkene.
2,2,3-trimethyl-3-bromopentane

Explanation

On reacting with sodium ethoxide in ethanol, the H-atom from `beta`-carbon atom is eliminated. This is called `beta`-elimination. Simultaneously, elimination of halogen atom from `alpha`-carbon takes place.
