Concept introduction: The elimination reaction is the organic reaction in which two substituents are removes from the organic molecule in one step or two steps. The two mechanism of the elimination reaction are E1 and E2 mechanism.

In E2 mechanism, the elimination takes place in one step.

The dehydrohalogenation reaction of the organic compound results in the formation of alkenes. They occur by the elimination of hydrogen halide.

The stereo specificity is the property of the reaction that the formation of different stereo isomeric products formed from the different stereo isomeric reactants.

To determine: The alkenes and the chemical reactions for the formation of these alkenes when (2S,3S)-3-bromo-2,3-diphenylpentane, (2S,3R)-3-bromo-2,3-diphenylpentane reacts with solution of sodium ethoxide in ethanol and the stereo specificity explanation of the reactions.
