When acetic acid is treated with trifluoroacetic anhydride followed by treatment with ethanol, ethyl acetate and trifluoroacetic acid are produced. Explain by mechanism each reaction and account for why ethyl trifluoroacetate and acetic acid were not formed. O CF 3 O O F 3 C O CF 3 O O OH O O OH O + + F 3 C OH O 6.
