The top half of the image depicts the reaction of the synthesis of
N,N-diethyl-m-toluamide (DEET). The bottom half of the image
attached shows the table of chemicals used in the reaction. How
would I calculate the theoretical yield and furthermore, the
percent yield? This experiment had a lot of chemicals used, and I
don't know where to start.
