IZ Os= n NaBr, Nacio EtOH/CH2COOH соон | 0 acetanilide The p-bromoacetanilide Which of the following are correct about the NMR of the materials above? Select all that apply. The NMR of acetanilide and p-bromoacetanilide are identical. The NMR of acetanilide would show a doublet at 7.49 with an integration of 2; a triplet at 7.30 with an integration of 2 and a triplet at 7.07 with an integration of 1. The NMR of p-bromoacetanilide would show a doublet at...
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. .
