Q. Which of the following species has a linear shape ?
A) NO₂⁻
B) SO₂
C) NO₂⁺
D) O₃
Explanation
[Solution from source] NO₂⁺ has two bond pairs and no lone pair on N (sp hybridised), like the isoelectronic CO₂, so it is linear. NO₂⁻, SO₂ and O₃ each have a lone pair on the central atom and are bent. Answer (3).
