Question Explanation: Find out the correct decreasing order of rare of electrophilic aromatic substitution reaction of given aromatic compounds.

Concept : This question is based on rate of electrophilic aromatic substitution reaction.

Solution:

Electron-releasing groups (+M, +R, +I, +H.C.) activate the benzene ring, increasing the rate of electrophilic aromatic substitution.

In contrast, electron-withdrawing groups (–M. –I) deactivate the ring, reducing the rate of electrophilic aromatic substitution.

Final Answer:

The correct option is (2)
