What would you expect to be the major product obtained from the following reaction?
Understand the Problem
The question is asking which product (I, II, III, IV, or V) will be the major product from a chlorination reaction involving a specific aromatic compound and FeCl3 as a catalyst. The focus is on understanding electrophilic aromatic substitution reactions.
Answer
III
The major product of the reaction is compound III based on the directing effects of the existing substituent.
Answer for screen readers
The major product of the reaction is compound III based on the directing effects of the existing substituent.
More Information
The reaction involves the use of FeCl3 and Cl2, facilitating an electrophilic substitution on the aromatic ring. The existing group directs the new substituent to a position that is either ortho or para, with para being sterically favorable in this context.
Tips
A common mistake is to overlook the directing effects, leading to choosing a meta product instead of ortho or para.
