(a)
Interpretation:
To supply necessary curved arrow(s) to convert the resonance structure on the left into the one on the right.
Concept introduction:
In the two species, the bonds are delocalized. This delocalization of bonds in species can be explained using resonance concept. Resonance exists in species for which there are two or more valid Lewis structures. For such species, each valid Lewis structure is called a resonance structure or a resonance contributor. The delocalization is shown using curved arrows.

- What would be the best choices for the missing reagents 1 and 3 in this synthesis? 1. PPh3 3 2. n-BuLi • Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine.

Additional inorganic or small-molecule reactants or products (like H2O) are not shown. In the drawing area below, draw the skeletal ("line") structures of the missing organic reactants X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure.
