Which is more polar 3-nitroaniline or 3-nitroacetanilide. Explain
How could you prepare a p-nitroaniline from the product; p-nitroacetanilide?
Which is more polar, Acetone or Water? Explain why.
Which of the nitroaniline isomers, the ortho-nitroaniline or para-nitroaniline, is the major product? Clearly state your evidence for your answer.
Problem 1: para-Nitroaniline is an order of magnitude less basic than meta-nitroaniline. Explain the observed difference in basicity. Also, would you expect the basicity of ortho-nitroaniline to be closer in value to meta-or para-nitroaniline (5 points)

4. Will a more polar or more non-polar molecule elute off a column first in reverse phase hy? Explain the rationale by which you made your choice (hint: again, include intermolecular forces in your explanation and include an illustration.).
Acetanilide, which has a molar mass of 135.17 g/mol, can be nitrated to nitroacetanilide, which has a molar mass of 180.16 g/mol, by the addition of nitric acid. What is the theoretical yield (in g) of the mononitrated product, nitroacetanilide, from 0.499 g of acetanilide?
Acetanilide, which has a molar mass of 135.17 g/mol, can be nitrated to nitroacetanilide, which has a molar mass of 180.16 g/mol, by the addition of nitric acid. What is the theoretical yield (in g) of the mononitrated product, nitroacetanilide, from 0.503 g of acetanilide? Answer:
5. What is the function of the charcoal in the purification of the 4-nitroaniline? (3 marks) 6. Why it is not possible to obtain 2- and 4-nitroaniline by direct nitration of aniline? (3 marks) 7. Explain with the use of appropriate resonance structures, the regioselectivity of the electrophilic aromatic substitution reaction - i.e. why is electrophilic aromatic substitution of acetanilide less favoured at the 3-position than at the 2- or the 4-positions. (6 marks) 8. Predict how a 'H NMR...
