We're being asked to draw the structures of A and B in each reaction sequence.
Recall that organometallic reagents can be prepared by the reaction of an alkyl halide with Mg or Li/Cu in a nonpolar solvent.
Grignard Reagent = R–MgBr
Gilman Reagent = R2–CuLi
Note that Grignard reagents (RMgBr) are strong bases, which means they should not be exposed to any acidic protons.
Draw structural formulas for organic products A and B in the window below.
