The number of anti - bonding electrons present in `O_(2)^(-)` molecular ion is :

A

8

B

7

C

5

D

4

Text Solution

Verified by Experts

The correct Answer is:
C
`O_(2)^(-):KK(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi2p_(x))^(2) (pi2p_(y))^(2)(pi^(**)2p_(x))^(2)(pi^(**)2p_(y))^(1)`
No, of electrons in antibonding orbitals = 5 (excluding inner orbitals = KK).
