Among the following , the paramagnetic compound is :

A

`Na_(2)O_(2)`

B

`O_(3)`

C

`N_(2)O`

D

`KO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Na_(2)O_(2) is (2Na) (O_(2)^(2))`. Thus is no unpaired either on `Na^(+) or O_(2)^(2)`. Hence it must be diamagnetic `O_(3) and N_(2)O` have even numbered electrons and thus are diamagnetic
