Is the following statement true or false? Why?
The amino group is an ortho/para director, but nitration of aniline produces the meta isomer predominantly.
Identify the stronger nucleophile.

List the following substituted benzenes in decreasing order of reactivity in an electrophilic aromatic substitution reaction.
Arrange the following compounds in decreasing order of reactivity toward electrophilic aromatic substitution.
Determine which of the following compounds is most and least reactive toward electrophilic aromatic substitution.
Determine which of the following compounds is the most reactive and which is the least reactive towards electrophilic aromatic substitution.
Why does aniline react faster than phenylphosphine in electrophilic aromatic substitution?
1,4-dimethoxybenzene (0.50 mol) and chlorobenzene (0.50 mol) were mixed together and reacted with 0.50 mol of nitronium ions until all of the nitronium ions were consumed. As a result, two products were obtained in amounts of 0.45 mol and 0.05 mol. Draw the major and minor products.
Draw the structure of the products formed when cyclopentanecarbaldehyde reacts with zinc amalgam in dilute HCl.
Phenol is brominated under much milder conditions than benzene. Draw resonance forms of the sigma complex that is formed after the electrophilic attack to describe why phenol reacts faster than benzene.
What major product is expected from the reaction shown below?
How would you accomplish the synthesis of 1-butyl-4-methylbenzene from toluene?
Purpurin is a dye that was originally isolated from madder root. If you nitrated purpurin using the reaction below, at which carbon would you expect the nitro group to attach?
