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
The paramagnetic substances are those which are freely magnetised in same direction as manetic field. All the species which have unpaired electrons or odd number of electrons are paramagnetic `KO_(2)` is paramagnetic because as it odd number of electron (s) (35 electron(s)).
`SiO_(2)` (30 electron (s)), `TiO_(2) `(38 electron(s)), `BaO_(2)`(72 electrons(s)). All are diamagnetic as they have all paired i.e. even number of elecrtrons.
