Smallest intermolecular distance is found in
Options
- AO ₂
- BO ₂⁺
- CO ₂⁻
- DO ₂²⁻
Correct answer
B. O ₂⁺
Step-by-step solution
In O ₂ , the bond order =2 In O ₂⁺ , the bond order =2.5 In O ₂⁻ , the bond order =1.5 In O ₂⁻² , the bond order =1 As the bond order in O ₂⁺ is highest, so its internuclear distance is smallest.
