The compound below was found to possess a large dipole moment, and resonance structures A & B were А B Neither structure A nor structure B can explain the observation. Structure B is very unimportant to the real structure, Structure A is very unimportant to the real structure, The original structure adequately explains the observation. Both structures A & B explain the observation Moving to another question will save this response.

The following two drawings are resonance structures of one compound. a-o But the following two drawings are not resonance structures Not resonance structures They are, in fact, two different compounds. Choose the correct explanation(s). Select all that apply. Benzene does not have three C-C single bond and three C-C double bonds. In fact, all six C-C bonds of the ring have the same bond order and same length. Benzene have three C- single bond...

5. Resonance provides the basis for a large portion of organic chemistry and helps us identify sites of high and low electron density. We will see that the electron source (nucleophile) is attracted to the site of electron sinks or deficiency (electrophile). For the following, draw the curved arrow that shows the movement of electrons that takes you from one resonance structure to the other. Remember to always start your arrow at the source of electrons (r-bond or lone pair)....

a. Circle the chiral centers in the following molecule and identify them as R or S Suggest a second component for synthesis of the molecule above via a Diels-Alder reaction (i.e. completer the reaction below) c. Is the configuration of your starting material in part b, E or Z? d. The concept of aromaticity (i.e. 4n + 2 pi electrons stable, aromatic; 4n electrons = unstable, antiaromatic) can be used to understand reaction like the Diels-Alder and related reactions. Use...
