In the molecular orbital description of the CO molecule (with the CO bond along the z-axis), which of the following statements correctly describes the Lowest Unoccupied Molecular Orbital (LUMO)?

Identify the correct statements about dioxygen species from the following: (A) 1Δg singlet O2 has both electrons in the same π* orbital. (B) 3Σg− ground state O2 has electrons in different degenerate π* orbitals with parallel spins. (C) 1Σg+ singlet O2 is lower in energy than 1Δg. (D) 1Δg O2 is responsible for photochemical reactions in the atmosphere.

According to Molecular Orbital Theory, what are the bond order and magnetic property of the N2+ ion?
