Expanded structure formula and Lewis dot structure. Some adsorption may occur in high organic-content peat or clay(3,4). Draw the best Lewis structure of [(CH 3)3O] +); fill in any nonbonding electrons. The resulting structure violates several conventions. A Lewis base is a species that has a non-bonding pair of outer-shell electrons that can be shared in a chemical reaction. The -NH 2 part of CH 3 NH 2 is called an amine functional group.
