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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
`{:("",O_(2) , O_(2)^(-), O^(2-),O_(2)^(+)),("Bond order :",2,1.5,1,2.5):}`
Greater the bond order, greater is the stability
Hence , decreasing order of stability is
` O_(2)^(+) gt O_(2) gt O_(2)^(-) gt O_(2)^(2-)`
