Alkene Reagent Selection

In each reaction box enter a letter designating the best reagent and conditions selected from the list on the right of the page.
Remember, the hydroboration and oxymercuration reactions take place in two independent steps; therefore, in these cases two reagents must be entered in the answer box in the correct order.
