The magnetic moment of `KO_(2)` at room temperature is ---------- BM.

A

`1.73`

B

`1.41`

C

`2.64`

D

`2.23`

Text Solution

Verified by Experts

The correct Answer is:
A
Potassium superoxide `(KO_2)` contains superoxide ion `(O_2^(-))` which has 1 unpaired electron. Therefore,
`mu=sqrt(n(n+2))BM=sqrt(1(1+2))=sqrt3=1.73BM`
