For each of the given compounds, the contributing resonance structures and resonance hybrid are to be written by adding missing unshared electron pairs and curved arrows. Concept introduction: Resonating structures are structures that have more than one equivalent Lewis structure for the same molecule or ion. According to the convention, these structures are connected by double-headed arrows ( ↔ ). Movement of electrons (whether bonding or lone pair) is indicated by curved arrows. The rules for writing the resonance structures are: Resonance structures have existence in paper only, they are not real structures. While writing the resonance structures, movement of either double bonded electrons or lone pair of electrons are shown. All structures should be correct Lewis structures. The energy of any contributing structure is higher than the energy of the resonance hybrid. For equivalent resonating structures, the resonance stabilization is large.

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures. Compound C Possible conformations (circle one): Дет
