The peroxide ion has no unpaired electrons.
Explanation:
- Peroxide ion is represented as O₂²⁻.
- This ion has a book shaped structure which is because of the lone pairs of electrons.
- The radicle contains no free electrons which can be proved if we look at the electronic configuration of the radicle.
- O₂²⁻(18)=σ1s2, σ∗1s2,σ2s2, σ∗ 2s2,σ2pz2 ,π2 px2.
- So here we see that each orbital of 1s,2s and 2p are full of paired electrons.
- So peroxide ion has no unpaired electron.
- Its also evident because peroxide is diamagnetic.
