RbO(2) is a...

`RbO_(2)` is a

A

peroxide and diamagnetic

B

superoxide and paramagnetic

C

superoxide and diamagnetic

D

peroxide and paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
B
Rubindium surepoxide `(RbO_(2))` contains superoxide ion `(O_(2)^(-))` which contains one upaired electron in the antibondingmolecular orbital. This makes `RbO_(2)` paramagnetic.
