Text Solution

Verified by Experts

The correct Answer is:
D
Bonding and antibonding orbital in `O_(2)^(2-)=18`

Electronic configuration of `O_(2)^(2-)` molecule.
`(sigma1s)^(2),(sigma^(**)1s)^(2),(sigma2s)^(2),(sigma^(**)2s)^(2),(sigma2p_(z))^(2)`,
`(pi2pi_(x)^(2)=pi2pi_(y)^(2)),(pi^(**)2p_(x)^(2)=pi^(**)2p_(y)^(2))`
