Number of paired electrons in `O_(2)` molecule is .

A

`16`

B

`14`

C

`8`

D

`7`

Text Solution

Verified by Experts

`MO` configuration of `O_(2)(Z =8)implies (8+8=16 e^(-))` is
`(sigma1s^(2))(sigma^(**)1s^(2))(sigma2s^(2))(sigma^(**)2p_(z)^(2))(pi2p_(x)^(2))(pi2p_(y)^(2))(pi^(**)2p_(x)^(1))(pi^**2p_(y)^(1))`
Therefore `O_(2)` molecule have 14paired and 2unpaired `e^(-')s` .
