NEET Chemistry Molecular Orbital Theory MCQ Question
Which of the following statements is not correct from the view point of molecular orbital theory?
Be₂ is not a stable molecule.
He₂ is not stable but He₂⁺ is expected to exist.
Bond strength of N₂ is maximum amongst the homonuclear diatomic molecules belonging to the second period.
The order of energies of molecular orbitals in N₂ molecule is σ2s < σ2s < σ2pₓ < (π2pₓ = π2pᵧ) < (π2pₓ = π2pᵧ) < σ2pᵤ.
Correct Answer
Detailed Explanation
The correct order of molecular orbital energies in N₂ is σ2s < σ2s < σ2pₓ < (π2pₓ = π2pᵧ) < σ2pᵤ < (π2pₓ = π2pᵧ).
