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
`KO_(2)` contains `O_(2)^(-)` ion which has one unpaired
electron . Hence
`mu= sqrt(n (n + 2) )BM= sqrt(1(1+2))`
`sqrt(3) = 1.73` BM .
