Draw Lewis structures to determine which of the following
compounds exhibit resonance. Enter the letters corresponding to all
those compounds which exhibit resonance. (If you find that choices
A, C, and F all have resonance and the others do not, for example,
you would enter ACF as your answer. Make sure the letters you enter
are in alphabetical order, with no spaces or commas separating
them.)
