Question

Which of the following statement is not correct from the view point molecular orbital theory?

Options

• 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 σls² σls², σ2s², σ2s^*, `π2p_x^2 = π2p_y^2, σ2p_x^2`

Answer 1

Bond strength of N₂ is maximum amongst the homonuclear diatomic molecules belonging to the second period.

Explanation:

Both \[\ce{SO^{2-}4}\] and \[\ce{BF^{-}4}\] are tetrahedral.
