  1. Do you want A substance that can be both a Lewis acid AND a Lewis base or do you want to classify each material listed as a Lewis acid or Lewis base.

  3. Draw the Lewis electron dot structure and it will help you decide.
    A Lewis acid is an electron pair acceptor. A Lewis base is an electron pair donator.
    I^- has any of four pairs to donate.
    BCl3 is one of those compounds with too few electrons (it doesn't obey the rule of eight) and it can accept a pair of electrons.
    NH3 has a pair of unused electrons it can donate.
    You look at the others.
