The formation of alkene 2-phenyl-2-butene is E or Z has to be explained from tosylate of (2R,3R)-3-phenyl-2-butanol via E2 elimination, similarly, the formation of alkene 2-phenyl-2-butene is E or Z has to be explained from tosylate of (2S,3R) and (2S,3S) tosylates -3-phenyl-2-butanol via E2 elimination. Concept introduction: Elimination reaction: An elimination reaction is removal of two substituents in a molecule and forms alkene. An elimination reaction is one or two-step process which based on the mechanism when two substituents removed from the molecule in single step is called E2 reaction. When two substituents are removed from the molecule in two steps is called E1 reaction. E2 elimination: Alkyl halide forms an alkene from the abstraction of the proton from the Î²-carbon atom followed by elimination of the bromine in a single step. Given information: The given compound is shown below,
