i have no idea how to do this! please help me :)

1a. When sodium benzyloxide is reacted with excess acetic anhydride it produces benzyl acetate and byproducts. What are those byproducts? If extracting with dichloromethane, what could be added to the aqueous layer to sequester the byproducts? Which layer would be on top, the aqueous layer or organic layer?
