Question

Decreasing order of stability of O₂ O₂⁻ ,O₂⁺ and O₂²⁻ is :
(a)O₂⁺ > O₂ > O₂⁻ > O₂²⁻ [2015 RS]
(b) O₂²⁻ > O₂⁻ > O₂ > O₂⁺
(c) O₂ > O₂⁺ > O₂²⁻ > O₂⁻
(d) O₂⁻ > O₂²⁻ > O₂⁺ > O₂​

Answer 1

Answer:

(a)O₂⁺ > O₂ > O₂⁻ > O₂²⁻

Explanation:

as we know , greater the bond order , higher is the stability ....

as Bond orders are 02-(2).....02-(1.5)....O2-²(1) .....O2+(2.5)

...

hope it helps
