Which of the following substituents will direct the incoming group to the ortho/para position during electrophilic aromatic substitution?

Question

Quizplus · Accepted Answer

The -CH3 and -OCH3 groups are known as ortho/para directors, as they donate electron density to the ring, making the ortho and para positions more electron-rich and therefore more reactive towards electrophilic attack. The -CH₂- and -CF3 groups are known as meta directors, as they withdraw electron density from the ring, making the meta position more electron-deficient and therefore more reactive towards electrophilic attack. The -COOCH3 group is also a meta director. Therefore, only choices A and C contain one of the two ortho/para-directing groups, and choice E contains both.
