During change of O(2) to O(2)^(2-) ion, ...

During change of `O_(2)` to `O_(2)^(2-)` ion, the electrons add on which of the following orbitals ?

A

`pi" orbital"`

B

`sigma^(**)" orbital"`

C

`sigma" orbital"`

D

`pi^(**)" orbital"`

Text Solution

Verified by Experts

The correct Answer is:
D
configuration of `O_(2)^(-)` is
`KK sigma(2s)^(2)sigma^(**)(2s)^(2)sigma(2pz)^(2)pi(2px)^(2)(2py)^(2)pi^(**)(2px)^(2)pi^(**)(2py)^(1)`
