The paramagnetic species is

A

`KO_2`

B

`SiO_2`

C

`TiO_2`

D

`BaO_2`

Text Solution

Verified by Experts

The correct Answer is:
A
`KO_2` is a superoxide of potassium containing superoxide ion, `O^(2-)` which has a three electron bond. Thus this ion can be represented as `[:underset(..)Ooverste((...)ul underset(..)O:]`
. The presence of one unpaired electron in three electron bond makes this ion paramagnetic.
