A graduate student trying to synthesize a bromine containing starting compound (Compound A) which is not commercially available. However, their advisor is forcing them to prove they synthesized the compound correctly by reacting it with different reagents.

The student determined that compound A is achiral based on an experiment where it was subjected to plane polarized light. When compound A is reacted with sodium ethoxide it yields only one product (compound B). Using spectroscopy the student determined that the molecular formula of compound B would be C7H14. However, if compound A was treated with tBuOK instead it generated a different alkene, as determined by spectroscopy.
