Draw structural formulas for all the alkene(s) formed by treatment of each haloalkane or halocycloalkane with sodium ethoxide in ethanol. Assume that elimination occurs by an E2 mechanism. Use the wedge/hash bond tools to indicate stereochemistry where it exists. If more than one structure fits the description, draw them all. Separate structures with signs from the drop-down menu.
