Question

Pre-lab questions 1. What is the expected product of the given monobromination EAS reaction? (See p 316-317 if you haven't studied aromatic chemistry yet in CHEM 241B.) 2. This aromatic ring is considered to be "activated" for electrophilic aromatic substitution. Draw resonance structures of acetanilide to determine if the NH- C(O)CH3 group is electron-donating or electron-withdrawing. 3. Bromine is produced in situ to react with the aromatic ring. What is the redox reaction that occurs between NaClO (in bleach) and NaBr in acetic acid to form Br2? NOTE: Use your general chemistry skills to complete the five equilibria reactions below and then write a final balanced equation. Think about what you start and end with to write the overall reaction. H2O 2 CH3CO2H _ _ 2 NaCIO + H20 HOCI + HOCI + Br HOBr + HOBr + H+ + Br2 + H20 Overall reaction.

Answer 1

PAGE NO DATE -CH3 H2 - CH₂ H. EN-C-CHa group is electon darating and hence activates the aromatic sing towards Electrophilic substitution reaction.
