Bromination of Acetanilide In a 25-mL Erlenmeyer flask, dissolve 0.68 g of acetanilide in approximately 4 mL glacial acetic acid. Record the exact amount of the limiting reactant that you used. Add a stir bar followed by 1.6 g pyridinium tribromide. Heat the mixture to ~60°C in a warm water bath for 10 minutes. After the 10 minutes, add 15 mL water and approximately 2 mL saturated sodium bisulfite solution to remove excess bromine, which shows by the disappearance of...

Below are three possible mechanisms for the bromination of
trans-stilbene. All mechanisms are possible on paper. Study each
mechanism and decide what the stereochemical outcome of each would
be and draw the appropriate product (syn, anti, or a mix of both).
Decide which mechanism is most consistent with your data from the
experiment. This work should all be recorded in your lab
notebook.
