During change of O₂ to O₂⁻ ion, the electron adds on which one of the following orbitals?
Options
(a) π* orbital
(b) π orbital
(c) σ* orbital
(d) σ orbital
Correct Answer:
π* orbital
Explanation:
O₂ = KK (σ2s)² (σ*2s)² (σ2pₖ)²
(π2pᵢ)² (π2pⱼ)² (π*2pᵢ)¹ (π*2pⱼ)¹
O₂⁻ = KK (σ2s)² (σ*2s)² (σ2pₖ)²
(π2pᵢ)² (π2pⱼ)² (π*2pᵢ)² (π*2pⱼ)¹
