996We can say that with a formula of O2-2, there are simply an odd number of electrons in the anion (6 e- + 6 e- + 1 e- = 13 e- ) . From a molecular orbital explanation, the peroxide ion has a molecular orbital configuration of σ1s(2) σ*1s(2) σ2s(2) σ*2s(2) σ2p(2) π2py(2) π*2py(2) π2py(1) π*2py(1) σ*2p(0). The unpaired electron in the pi* orbital accounts for the paramagnetic behavior or potassium superoxide.
Anurag Ghosh Swarna u wrote O2^2- has odd no. of electrons dat is 13....It should be O2^-- Swarna Kamal Dhyawala @anurag
ooooo thank u it will be -1 only
- Anurag Ghosh Cool Swarna..:)
