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

A

`1.41`

B

`1.73`

C

`2.23`

D

`2.64`

Text Solution

Verified by Experts

The correct Answer is:
B

Magnetic `mu = n sqrt(n(n+2))BM`
where n is the number of unpaired electron.
`KO_(2)` has 1 (one) unpaired electron
`mu = sqrt(1(1+2))BM`
`sqrt(3) = 1.73BM`
