Starting with the Kekulé structure below for 2-methoxy- phenanthrene, determine which one of the three ring positions (a, b, or c) would show the major product upon nitration ("NO) in an electrophilic aromatic substitution reaction. You should use the resonance structures of the reactant prior to attack of the electrophile. Electron flow has been started for you.

Post Lab Questions for Nitration of Acetanilide, Nitration of Methyl Benzoate, Nitration of Phenylacetonitrile, Nitration of Phenol. 1. What product(s) do you expect to be formed in the nitration of phenol? Why? 2. All three of the nitrophenols have boiling points well above 200°C. Explain clearly why it was possible to distill something with such a high boiling point when the temperature of the distillate never rose much above 100°C. 3. What product did you actually obtain in the distillate?...

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...

Conceptual Checkpoint 18.32 The presence of additional nitro groups can have an impact on the temperature at which a nucleophilic aromatic substitution will readily occur. Consider the following example Cl он 1) NaOH 2) Hyo NO2 NO2 When both R groups are hydrogen atoms, the reaction readily occurs at 130°C. When one of the R groups is a nitro group, the reaction readily occurs at 100°C. When both R groups are nitro groups, the reaction...
