Paramagnetism is exhibited by :...

Paramagnetism is exhibited by :

A

`N_(2)`

B

`O_(2)`

C

He

D

`O_(2)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
B
Paramagnetism is observed due to the presence of unpaired electron(s).
`therefore ` in case of `O_(2)` we have
`O_(2): K K^(**) L L^(**) (sigma 2p_(z))^(2) (pi 2p_(x))^(2) (pi 2p_(y))^(2)(pi^(**)2p_(x))^(1) (pi^(**)2p_(y))^(1)`
Two unpaired electrons. In other cases, we have no unpaired electron(s)
