(a)
Interpretation:
The electron-rich sites and electron-poor sites in the given elementary steps are to be identified.
Concept introduction:
An atom with partial or full negative charge is an electron-rich site whereas an atom with partial or full positive charge is an electron-poor site. In an elementary step, electrons tend to flow from an electron-rich site to an electron-poor site.
(b)
Interpretation:
In each of the given elementary steps, the appropriate curved arrows are to be drawn.
Concept introduction:
The curved arrow can be drawn from an electron-rich site to an electron-poor site to show the flow of electrons from the electron-rich site to the electron-poor site. The first curved arrow is drawn from the lone pair of the negatively charged atom of the electron-rich site to the less electronegative atom of the electron-poor site. The second curved arrow is drawn from the region between the less electronegative atom and more electronegative atom towards the more electronegative atom, indicating the breaking of the bond.
(c)
Interpretation:
The names of each elementary step are to be identified.
Concept introduction:
In the bimolecular substitution reaction
In nucleophilic addition step, the nucleophile adds to the polar
In the nucleophilic elimination step, the more electronegative atom bears full negative charge or partial negative charge. This electronegative atom forms a

Neutralizing work-up Select to Drawarrow_forwardb) 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.
