Consider the electrophilic aromatic substitution reaction: 

Predict its product.

Draw the resonance structure(s) that show(s) why the carbonyl group is not an ortho/para–director.

Draw the monochlorinated product(s) from the reaction of the compound below with one equivalent of Cl₂ in the presence of FeCl₃.

Which position is the most susceptible to an electrophilic attack on the following benzene derivatives?

What is the major product when the compound shown below reacts with Cl₂ and AlCl₃?

Biphenyl is an aromatic compound having two benzene rings joined by a single bond. The site of an electrophilic aromatic reaction is usually the one that is on the more activated ring. The other ring and other substituents (if present) also affect the reaction regiochemistry.

Predict the major product of a monochlorination reaction for the following compound:

Will bromination occur at the ortho, para, or meta position with respect to the pyrimidinium ion in the reaction below? Explain.
