Solution: The following alkyl halide has unknown stereochemistry at the position indicated. Upon undergoing an E2 reaction the single product formed is the alkene shown. Indicate the stereochemistry of the starting materials that would allow for this alkene to form as the exclusive product. Draw a Newman projection down the central bond indicating the relationship between the groups to help support your answer.
