Given below are two statements.
Statement I: O₂⁺, O₂, O₂⁻ and O₂²⁻ are paramagnetic in nature with bond order 2.5, 2, 1.5 and 1 respectively.
Statement II: The lowest unoccupied molecular orbital (LUMO) for O₂ is σ*2pz.
In the light of above statements, choose the most appropriate answer from the options given below.
O₂²⁻ is diamagnetic in nature.
Electronic configuration of O₂
= σ1s², σ*1s², σ2s², σ*2s², σ2p_z², π2p_x² = π2p_y², π*2p_x¹ = π*2p_y¹
Hence LUMO for O₂ is σ*2p_z.
