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

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
C
Stability `prop`bond order
`O_(2) implies sigma 1s^(2) sigma^(**)1s^(2)sigma2s^(2)sigma^(**)2s^(2)sigma2p_(z)^(2)`
`(pi2px^(2)=pi2py^(2))(pi^(**)2px^(1)=pi^(**)2py^(1))`
bond order `=(N_(b)-N_(a))/(2)`
Bond order `=(6-4)/(2)=2`
