Provide a detailed, stepwise mechanism for the reaction below. (CH$_3$)$_2$CHCH$_2$CH$_2$CH$_2$I + CN$^-$ $\rightarrow$ (CH$_3$)$_2$CHCH$_2$CH$_2$CH$_2$CN + I$^-$ Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the canvas and connecting them with bonds. Add charges where needed. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created.
