Write a mechanism for the formation of N-(2, 4-dinitrophenyl) aniline via nucleophilic aromatic substitution. Show all resonance forms that stabilize the intermediate in this reaction.
One model of the hydrogen atom relies upon the idea that the electrons reside in stable orbits from which they can not deviate and are found outside of a small, densely packed group of protons. This model was created by
4-methoxybenzoic acid is a weaker acid than benzoic acid, but methoxyacetic acid is a stronger acid than acetic acid. Explain this apparent contradiction.
