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.)

Prelab questions:1. Make sure the reaction table described above is completed in your notebook.2. Two benzaldehyde molecules combine with one acetone molecule in this aldol reaction. If someone uses 5.0 mL of benzaldehyde and 2.5 mL of acetone to try to improve the yield of product, is this the correct ratio of molecules so that there is no excess? Why or why not?The Aldol Reaction: Synthesis of DibenzalacetonePurpose: Introduce the student to the hands-on chemistry of carbonyl condensations.Warning: Dispose of...
