Which of the following is not an ortho-para director in electrophilic aromatic substitution?
Understand the Problem
The question is asking to identify which of the given groups does not act as an ortho-para director in electrophilic aromatic substitution reactions. This involves understanding the effects of substituents on the aromatic ring and their directing influence in electrophilic substitution.
Answer
-CCl3
-CCl3 is not an ortho-para director in electrophilic aromatic substitution.
Answer for screen readers
-CCl3 is not an ortho-para director in electrophilic aromatic substitution.
More Information
-CCl3 acts as a meta-director due to its strong electron-withdrawing properties, making it unsuitable as an ortho-para director.
Tips
Assume electron-withdrawing groups typically direct to the meta position due to decreased electron density on ortho and para positions.
