AIIMS 2018 Chemistry Electrophilic Aromatic Substitution MCQ Question

Option C is correct because it accurately represents the molecular structure of nitrogen dioxide (NO₂), which features a bent geometry due to the presence of a lone pair on the nitrogen atom, leading to a bond angle of approximately 134°. The other options, despite being similar, may not depict the correct spatial arrangement of the atoms or fail to illustrate the resonance structures that contribute to the overall stability of NO₂, which is crucial for understanding its reactivity and properties. Understanding the molecular geometry of NO₂ is essential for predicting its behavior in chemical reactions and interactions with other species, such as H₂O or CO₂.
