Why superoxides of of alkali metals are paramagnetic ?

Text Solution

Verified by Experts

Superoxides of alkali metla contain `O_(2)^(Θ)` which contains a three electron bond `[overset(x)(x)overset(x x)(O)overset(x x x)_overset(x x)Ooverset(x)(x)]^(Θ)`, i.e. it has one unpaired electron and hence it is paramagnetic.
