AIIMS 2019 Chemistry Electrophilic Aromatic Substitution MCQ Question

In electrophilic aromatic substitution reactions, an amino group (–NH₂) is an o-p-directing group due to its ability to donate electron density to the aromatic ring through resonance, stabilizing the positive charge in the intermediate carbocation formed during the reaction. Option C illustrates the amino group positioned in such a way that it enhances the reactivity of ortho and para positions, making them more favorable for substitution. Other options may depict substituents that are either deactivating or meta-directing, which do not enhance the reactivity at the ortho and para positions, thus failing to demonstrate the o-p-directing nature of the amino group.
