Fill in the blanks with the single letter code of the appropriate reagent, or the appropriate descriptive vocabulary word/phrase to complete the description. Remember the computer is very literal so check your spelling carefully. First we add reagent ______ to from the ______ anion, then add reagent ______ to act as an electrophile for a ______ mechanism. Then we add reagent ______ followed by reagent ______ to give the product with ______ regioselectively. The initial product of this reaction series contains a(n) ______ functional group which rearranges to the final product via a ______ mechanism. If instead we wanted to form 2-pentanone we’d reagent ______ in the last step to add the oxygen with ______ regioselectivity
