1. Using what you know about valence electrons, chemical reactions, and full outer shells of electrons: Hydrogen has one electron, helium has two electrons, and lithium has three electrons. Hydrogen and
lithium are both reactive, but helium is nonreactive. How can electrons be used to explain this pattern of
behavior?

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
