For
each of the reactions, show the reafents that would best accomplish
the given synthesis, according to reactions we have atudied in
class. be sure to number your steps.

Provide an efficient synthesis for each product using reactions we have discussed this semester. It will be easier to award partial credit if you show the intermediates (i.e. product(s) after each synthetic step). You may use the reactant indicated and any reagents that contain seven (7) or fewer carbon atoms (this of course includes reagents with no carbon atoms) to complete your synthesis. If the reaction conditions (i.e. amount of reagent, temperature, etc.) are important, please be sure to specify....
