Draw the structure of the quaternary ammonium hydroxide resulting from methylation with three equivalents (or excess) of CH3I and silver oxide treatment of the given amine, give the mechanism of its elimination, and draw the major product(s) of the elimination reaction. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with bonds, including charges where needed. Indicate the mechanism by drawing the electron-flow arrows on the molecules. Arrows should start on an atom or a bond and should end on an atom, bond, or where a new bond should be created.
