On being heated with potassium ethoxide in ethanol (70 degrees C), the deuterium-labeled alkyl bromide shown gave a mixture of 1-butene, cis-2-butene, and trans-2-butene. On the basis of your knowledge of the E2 mechanism, predict which alkene(s), if any, contained deuterium.
Note that the absolute stereochemical configurations of chiral substances cannot be determined from the data. Arbitrarily draw a configuration for an enantiomer (and be consistent with the derivatives); omit wedge/dash bonds for a racemate.
