The above synthesis was designed using the Organic Chemistry Roadmaps in the appendix of your textbook. In this synthesis, reagents from the table (shown in blue) are used to carry out the indicated reactions. In the box below, draw the structure of compound b. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • Consider E/Z stereochemistry of alkenes. • If more than one structure fits the description, draw them all. • If a compound is formed more than once, add another sketcher and draw it again. • If the reaction produces a racemic mixture, draw both stereoisomers. Separate structures with + signs from the drop-down menu.

A. Determine whether the curved arrow(s) shown below generate a valid or invalid resonance structure. Draw the resonance structure that would result from each properly drawn arrow and identify the arrow pushing pattern (i.e. allylic positive charge, allylic lone pair, pi bond between atoms of a different electronegativity, lone pair adjacent to a positive charge, alternating pi bonds in a ring.
