In which of the following molecules, σ2p_z molecular orbital is filled after π2p_x and π2p_y molecular orbitals?

Question

In which of the following molecules, σ2p z molecular orbital is filled after π2p x and π2p y molecular orbitals? (i) O 2 (ii) Ne 2 (iii) N 2 (iv) F 2

(iii);

In the atoms having electron less than or equal to the 14 electrons, the σ2p_z molecular orbital is filled after π2p_x and π2p_y molecular orbitals.

Only nitrogen in the above options has 14 electrons other options have more than 14 electrons.

Thus, in nitrogen, the σ2p_z molecular orbital is filled after π2p_x and π2p_y molecular orbitals.
