Decreasing order of stability of O(2), O...

Decreasing order of stability of `O_(2), O_(2)^(-), O_(2)^(+)` and `O_(2)^(2-)` is

A

`O_(2)^(2-)gt O_(2)^(-)gtO_(2)gtO_(2)^(+)`

B

`O_(2)gt O_(2)^(2-)gtO_(2)^(2-)gtO_(2)^(2-)`

C

`O_(2)^(-)gt O_(2)^(2-)gtO_(2)^(+)gtO_(2)`

D

`O_(2)^(+)gt O_(2)gtO_(2)^(-)gtO_(2)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
D
`B.O. O_(2),O_(2)^(+),O_(2)^(-),O_(2)^(*2-)`
`2.0 0.5 1.5 1.0`
The stability of molecules/ions is directly proportional to bond order.
`therefore` Drcreasing order of stability is :
`O_(2)^(+)gtO_(2)gtO_(2)^(-)gtO_(2)^(2-)`
